I didn't find here the pinout description of 2,5mm jack connector from XDA2.
There is stereo out, microphone in and two buttons.
I tried to buy 2,5mm connector, but it is not usable - connector itself fits to the XDA2, but the connector's body is too thick so the connector can not be fully plugged in.
So i bought some Nokia portable handsfree, which is also equipped with 2,5mm jack with four pins. So all i need is to know, how it should be connected.
I also bought a small plastic box, two 3,5mm stereo females and two little buttons. All of those things will be installed into that tiny box (plus the Nokia 2,5mm male connector). So this will work as an universal adaptor: from XDA2 to anything. I already bought big HiFi earphones with built-in microphone - it has two male 3,5mm jacks - one for stereosound, second for the microphone - so I'll be able to connect it to the XDA2 using my homemade tiny box and HiFi telephoning will become the reality ;-))
I'd also like to make a "homemade" simple car handsfree : I'll connect XDA's audio out to AudioIn on my car audio (also suitable for playing MP3 from XDA on car audio system). And I'll connect a standalone external microphone to XDA, microphone will be placed somewhere in the cabine.
Does it sound insane? Or realistic? Does anybody know the XDA2 jack pinout?
http://xda-developers.com/connectors/
this is xda1 but they are suppose to be able to use the same headphones
so it would help a bit
even though the xda1 dont support the 2 button thingy
Hey, as I trashed my cable I had to find out a little bit about the connecter
I write this from memory, so please handle with care ;-) :
from top to bottom
top ring - stereo out (left or right)
next ring - stereo out (right or left)
next - microphone in
next - ground
metallic ring in the inside of the connector - phone switch
By the way.. these pins are protect versus each other.. you'll have some tries..
Alex
The truth is that I can use the system connector instead of the 2,5mm jack.
AudioOut and MicrophoneIn pins are on the system connector as well...
So meybe I'll make SystemConnector-to-3,5mmJack adaptor ;-)
Or is there a difference?
Ehm..I had simply buyed a 2,5 to 3,5 Jack and cut a piece of it to fit into phone:

Well, OK. But it is only a stereo out, you don't have a microphone in. I'd like both of them plus those two buttons (red and green phone button)...

this one have the mic but dont support the pickup and slam down of the phone
So meybe I'll make SystemConnector-to-3,5mmJack adaptor

well if you wanted to connect something else to the sysconnector you would not be able to connect something like charger or GPS
then imho it would make more sence using the 2.5 connection which cant be used for anything but sound anyway
Well, I am looking for such a device, but then one that will work with the XDA2/MDA2
Because I would like to use my own B&O headset, but would like to keep the phone function with microphone and answer buttons
So if somebody would like to spend an hour on the web for a detailed surch :wink:
make it your self...
takes less than 30 minutes (if you know how to use a solder iron)
I did it and I am trulty happy with it.
Alex
but is it not a problem that the lengh of the 3.5mm headset get added to the length of the wire from the device to the buttons and mic
i mean the mic need to be able to reach ones mough but the lenght from ones mouth to ones ears are not that long and with the added 3.5 mm headset lenght it would seme to become a wire mess?
Yes and No...
Yes if you do nothing.
No if you wrap it up a little.
well if you wrap the wire you will create a coil line effect
and that damage audio quality
just kidding i'm not a real audiophile
It seems that info in xda-developers.com/connectors/ is aplicable to XDA I.
XDAII headset has 2 buttons, answer and finish.
I'm specially interested in the 22pin pinout, that I've told IS DIFFERENT from the XDA I.
Can anybody point me with updated info on XDA II conneectors?
Thanks

Alex,
This is correct. The XDA II uses 5 pins instead of four. The switches are both connected to the 5th ring on the inside.
Until now, I wasn't able to find this connector.
Seems it's only used on the XDA II.
The diagram of the XDA I connector is correct, only the button isn't connected over the microphone to ground. So if you only need audio and mike, use that schematic.
Grtz,
Jos
Hola!
I'm trying to work out how to make my own XDA car kit cable. I have the pinout for the XDA - thanks to the XDA Developers Site
- http://wiki.xda-developers.com/wiki/Connectors
I also Have a pinout for the back of my Stereo (Philips CAR 400 From a Vauxhall Astra - '02) thanks to
- http://carradio.hit.bg/philips.htm
I have done some preliminary testing with small cables and connectors that go into a standard phono input on my big stereo in my room and have been successful at making a mini-kit, but am having real trouble working out what the pins on the back of the car stereo do (i.e which is for audio input from the phone)
Labels are as follows:
PHILIPS CAR400
01 - SVD
02 - SAC
03 - SCL
04 - Tel. Mute
05 - TIS
06 - Batt. +
07 - MRQ
08 - Power Antenna
09 - DDL
10 - Lights
11 - ACC ( 12 v + )
12 - GND
13 - SDA
The only one that make any sense is Tel. Mute (Anyone any idea what voltage I have to put accross this to get the system to mute)
If anyone knows what the rest of the pins stand for your help would be much appreciated.
Many thanks,
Will
You put the mute to earth to mute the stereo - normally it's floating.
1 down
Good good, one down, 12 to go.
Now I've read your question.
Answer is probably none of them. All the mute does is silence the audio (and pause the CD on some radios) - the assumption is either that you have a remote speaker for the phone or you use some commercial adapter like Autoleads to intercept the output to the car speakers via a relay. Autoleads sell a huge range of car/stereo specific leads that all provide a "generic" phone interface for Nokia phones. There are also a number of patch leads that enable you to plug specific car kits to the Nokia interface (which is just Battery, switched +, ground and mute with a 3.5mm jack for mono audio. Most knowledgeable guy for this stuff is Terry White on http://www.siocommunications.co.uk/ (he'll sell you the appropriate leads or make up what you need).
Note that the Autoleads solution (which mutes the stereo and uses relays to swich the audio from the phone to front speakers) renders the stereo automute unnecessary, but it is nice to pause the CD anyway and usually you get a front panel indication of phone call which is useful.
I note that the Philips connector also has an audio L/R/Gnd input. This is probably for an aux source like an MP3 player (eg XDA) but of course this needs to be selected on the radio and will also be muted when the mute pin goes to ground.
Hope that helps
I guess the other pins are things like CANBus, D2B wakeup etc. a bit like Siemens/Bosch
Last one. The Autolead you need is 06-078B - £47 + pp from Terry.
http://www.siocommunications.co.uk/06-078B.html
Phew!
That's a mighty big cable?
I notice that it has a 'big connector' (I've marked it in yellow on the image I've attached with this post). There is already one of these on the existing setup. This wouldn't mean I have to completely rip out all of the existing wiring would it?
Also, the jack (Red on the image) looks like a mono jack, I assume this is the bit that plugs into the phone or which I can adapt to plug into the phone?
Seems a bit expensive too, is it really necessary? Can I just forget the auto mute feature and have the phone output go through the 'MP3 In' inputs? That way I can listen to the music on the XDA through the car stereo as well as any sat-nav stuff I decide to install later on.
The main aim of my question is to try to develop a cheap solution to an XDA-Car audio interface. Do none of the connections on the back of my stereo allow me to wire in some sort of auxiliary input?
Yes it is big but it does the job and you can usually find room.
The connector(s) go in line with the ISO and stereo specific plugs, so routing all the power and speaker outputs via the relay module. You don't rip anything out, or need to break into existing wiring, so you reduce risk of problems or warranty issues - it really is the lowest hassle solution.
Yes the red plug is the phone audio input and is designed for Nokia kits.
Expensive? Not really, considering you avoid any hassles and can remove the kit after with no changes or damage to the car wiring. Replacing connectors and fixing car wiring can be expensive.
Yes you could go into the Philips cnnector from the XDA, but you would have to manually select Aux in on the radio, and it wouldn't mute anything. If you were listening to the car radio you'd need to answer the phone and also switch to aux in on the radio to hear anything. Sounds a mess to me!
OK
Ok, so assuming I use the new connector to wire in the phone and have it working through a seperate speaker, how do I connect the MP3 Outputs of the XDA into the stereo. I have no problem using a seperate speaker for the voice on the XDA but I really want to play the XDA music through the Car's built in speakers.
I understand I'll have to come up with some way of getting the sound from the XDA to the speaker AND the car stereo but I don't mind that, It's just something I'll have to worry about.
Most car stereos I've seen have a seperate set of Phono Sockets for auxiliary inputs but this philips doesn't. What do the pins on the back actually stand for in english? (Laymans terms please because I don't understand the long names but I will be able to fathom how to use them if you tell me what they actually do, long names might be ok too cos I can always look on Google to find out what the various bits do.)
Actually I screwed up - looking again at that wierd Bulgarian* site the CAR 400 looks like it has the 26 pin connector and the phone lead would be Autolead 06-053B.
http://www.siocommunications.co.uk/06-053B.html
Also it looks as though the CAR400 does NOT support Aux in - sorry about that - although you could try putting signals onto pins 9 and 10 (using 3 as Ground) and see what happens (that's what the CAR660 uses). No warranty actual or implied!!
* This guy is promoting software to crack EEPROM codes on car radios and to clock cars with digital instrument clusters. Not sure I'd be so keen to build a close relationship there mate!!
No Fear
Thanks anyway, I've got a few exams to sit this coming week so no chance to fiddle for a bit but I'll post back again once I work out how it goes. Looks like I'll have to find some sort of seperate amp and patch it in somewhere to output to the car speakers.
No connection between me and the Bulgarian bloke, just found the site on google as a means of showing you the pinout on the back of the CAR 400.
I'm assuming Pins 9 and 10 CDR and CDL stand for CD - Left and CD - Right respectively?
One last quickie before I go, can I source ISO connectors (Just the plastic bits) from anywhere so I can maybe make a patch through cable? I'd need a male and a female one.
i.e.
CAR STEREO (FEMALE ISO) ---> Wiring (MALE ISO)
becomes
CAR STEREO (FEMALE ISO) ---> NEW MALE ISO --------> MY STUFF ---------> NEW FEMALE ISO ---> Wiring (MALE ISO)
Cheers for the help, I'll have a mess about over the next few weeks and post back with my results in case anyone's interested.
Just a note to say I've found some ISO Connectors. You can get them from maplin.
http://www.maplin.co.uk
codes
QK25C (headunit end) @ £4.99
MZ76H (car end) @ £6.99
Anyone finds them a bit cheaper let me know...
Another quick note. I've found a small amplifier from Maplin (Code N67AW) 40W 6-16V. (MONO ONLY)
The instructions say it is a 'bridge type' amplifier and that the speaker connections should therefore not be to ground (As in a car).
The setup works fine on my test rig at home, but I was wondering, will I just get lots of noise if I connect it up in the car, or will I blow everything up?
So far my plan is to make a patch through cable that amplifies the XDA signal direct to the car speakers and has some form of automatic switch to detect if audio is coming through the XDA. If it is, then it mutes the signal from the car stereo and patches the XDA through.
Any suggetsions?
I used to have the original XDA (T-Mobile USA). I just bought the Cingular-branded Blue Angel (btw, they come unlocked).
As many have stated, the pinout for the headset is different. Here's how it's set up in the Blue Angel:
Sleeve - Ring 1 - Ring 2 - Tip
Ground - Out R - Out L - Mic In
As opposed to the original XDA:
Sleeve - Ring 1 - Ring 2 - Tip
Ground - Mic In - Out R - Out L
Now, I really need help to find the Audio in/out pins in the bottom connector. As far as I know (I checked), pin 1 is no longer Mic In.
Also, grounding pin 19 does not turn off the internal mic and speaker.
I'm a pro journalist - In the old XDA, the Mic In in the bottom connector gave me amazing sound from a Shure Microphone (through custom made cable with a line matching transformer).
I desperately need to know where's the Mic in and Audio Ground in the bottom connector. The Mic In in the top headset connector doesn't provide clean sound.
Thanks everyone.
Hey Uspino,
I got the same problem. But i find out that the pinout for only the audio on the bottom is the same as on this page :
http://wiki.xda-developers.com/wiki/Connectors
I hope anybody can find out wich pin is the mic. This weekend i will try out, so maybe monday i have an answer.
Pin 12 builds up a voltage of 3V to 4V when you make a call.
BTW, do you have a loose 22-pins connector for the mdaIII and can you tell me where i can buy this? Now i take the connector wich is shiped with the MDA for charging. I confirm the pinout you find out for the top headset.
Thanks anyway!
I am attempting to house an i-mate PDA2 in a custom enclosure (for a product that we make). I want to modify the 22 pin connector on the sync/power cable but I cannot find a pinout.
I need a picture or diagram of the 3, or is it 4, rows of pins with pin numbers, pin function and connector wiring (jumpers, etc.)
Anyone know where I might find this?
Before you get crushed by the "rtfm" type posts, I humbly direct your attention to the "connectors" link on the front page of this site, which will lead you to: http://wiki.xda-developers.com/wiki/Connectors. It's an extremely useful page!
OK, I told you so now you tell me; what're you guys making?!
I did check out the "connectors" page and it is helpful.
However, what I am looking for are details of the inside of the cable connector. I took one of these connectors apart and it's not the easiest thing in the world to figure out which pin goes to which on the PDA side or what the number system is.
So, it would be very helpful to know if someone has already gone through the unravelling.
In a nutshell, our company has developed a technology that uses ultrasonics to measure load in bolts both during and after tightening. The PDA is the platform for the controller of the tightening and inspection tools.
Sorry, I assumed that you'd not looked at the connectors page because I used it to figure out (I think) what it is you're after when I was trying to make my own sync/charge/gps connector.
If this is something that you can't resolve with a multimeter, then I guess you must be looking at an interesting connector! I'd suggest posting a couple of pics of the connector with it's top off lined up with the phone's socket. That'll make it easier to figure out what's what!
The load detector sounds cool, I'd love to see a screenshot if you've got one.
Yes, it can be resolved with a multimeter - I was just looking for the lazy way out!
I have attached a photo of the prototype unit - not the most professional representation, but a decent one nonetheless.
That looks cool! I love it when people *really* use these things.
If you open the connector up and see 2 (staggered) rows of tiny, really hard to solder :lol: pins, pin 1 (left side of the phone connector if you hold it bottom towards you, screen up) is the bottom left pin.
_| | | | | | | | | | |

^ bottom left is pin 1. Hope this helps, sorry I had to bath the baby earlier and was typing whilst holding a somewhat sticky little girl
Thank you!
Subject: PDA2 sync/power cable connector pinout
On this thread, I was thinking of using the desktop cradle as the base for a mobile mount.
But the pin-outs for the PDA2k are not easily found.
The connector link now appears to be at:
http://wiki.xda-developers.com/index.php?pagename=Connectors
This page seems only to refer to the Wallaby and the Himalaya.
Is there a specific page for the PDA2k or does anyone know if the pin-outs of the 22 pin connector are the same for the Wallaby/Himalaya as they are for the PDA2k?
-I found elsewhere that Pin 19 was different.
Are there any other differences?
Also somewhere amongst the threads there was a mention of the pin-outs of the 2.5mm audio out /mic in was different or was it the switch on the hands free headset?
I have trawlled the site and it has eluded me so far for a consiolidated posting on the connectors for the PDA2k.
Can anyone point me in the right direction?
Perhaps I am just deluding myself
Thanks in advance
If you lost your marbles, would you know where to find them?
harrier mounts and connectors
I wouldn't use the desk cradle to make a car mount. IMO the car mount from Clicon (www.clicon.com.au) is better mechanically than the desk cradle, and already suited to vehicle mounting
There are a number of variants of their kits, but not many that suit my pda2k-evdo. The ones that do suit are:
- plain cradle with no connectors, but leaving the pda2k connector exposed and accessible
- plain cradle with "passthrough" connector - so connect your own charger etc to the bottom of it. Note that this passthrough doesn't support the two lugs that some pda2k plugs have (eg the charging dongle that came with the pda2k-evdo)
- cradle with lighter-socket charger. The charger part is actually removeable; they've just screwed the car charger to the cradle.
The lighter-socket charger mentioned above has a small board inside the connector with Tx and Rx holes labelled. It looks like it was designed for making a serial+charge adaptor.
I have a separate RS232+charger adaptor cable ("suits XDA IIs") which looks like it's charging, but really just keeps the screen on and runs down the battery quicker. It turns out it only has one V+ and one Gnd pin connected, as opposed to 3 of each listed on the Connector page on this site. Makes me wonder whether the 3 pins for V+ actually all have the same function. Time to mod the connector...
Gregnash,
I agree with your summary,
and I have looked at the available in car cradles/holders.
I have already ported a XDA1 cradel with audio/mic,USB and power to see if the connections can be done successfully.
All worked except for the mic as I need to find a 4 polo 2.5mm panel socket so that it switches on hook.(this I assume is pin 19)
You are right, by itself the Harrier cradle does not securely hold the pda in place as there is lateral movement.
What I am trying to achieve is a "all in one" in car cradle/holder.
I have sucessfully mounted a NOKIA passive anennae connector to a stand alone generic brand pda holder.
This as you said allows the connector to be exposed for charging.
I have used this method with a 9db external (old analogue antenna-funny that, you can use them for CDMA) antenna or a 9 db through glass antenna.
Currently the system is clumsy as also I run a bluetooth external GPS and route the audio from the 2.5mm socket to the cassette player adapter.
-(no audio IN in this car radio)
What I was hoping to do was to incorporate the Nokia Passive antenna coupler at the rear of the Harrier cradle which would put slight pressure in the forwards direction to both make an antenna connection and more secure and stop the Harrier from moving.
(Another flash idea is to strip the inductance plate from the coupler and mount a antenna cable socket on the coupler face so that it aligns with the antenna out from the Harrier)
With the audio out /mic in and charge through this connector , I am hoping to eliminate all of the wiring as I can conceal the wiring back inside the dash.
The only other thing is the on hook switch for receiving calls.
As you can probably guess I probably have too much spare time.
Perhaps Bluetooth In car kit will by-pass the need for the physical connectors as it is software driven.
But I have heard of so many bad reports of BT connecting to the phone that it appears to be pot luck if I find one that works.
What about this arrangement:
1. Harrier cradle -with antenna coupler if secure,
2. bluetooth in car (cigarette lighter style) hands free-Blue Ant etc,
3. audio out from cradle to radio ( for GPS instructions and playing mp3 from Harrier) freq transmitter(powered externally).
4. bluetooth GPS external antenna
mmmm..... maybe a bit of an ask but it does allow a "drop on cradle ,push forwards to engage antenna and forget" action.
Maybe I am off with the fairies, what do you think?
Any comments would be appreciated.
For antenna supplies you can try this site http://www.wpsantennas.com/ basically I think it would boost reception back to 3 watts. 3 watts is the same wattage as the old car mounted mobile phones. Mobile phones operate on 0.5 watts. No wonder our reception sucks in so many places.
Hook the antenna into a car cradle and some type of handsfreee switch for the radio, and you have a very powerful, very mobile 3 watt mobile phone with great reception.. if you got carried away you could even connect your car to the ppc and moniter engine, fuel, etc. Plus a GPS.. and oh the possibilties are endless.
Johnno's ambitious car kit
Yeah, I think you do have too much time on your hands
Sounds like a plan, though, and I'd like to know if you make it all work. The antenna couplers I've seen take a bit too much force for a "drop in, push back" arrangement, but one designed for a different phone may do the trick if it fits.
btw, my interest in serial is for wired GPS and to talk to the engine management computer (not at the same time, or one will have to be bluetooth). Even better if they can be powered from the same cable.
dougnet
Thanks for the link.
I actually had thought of this proposal.
I actually contacted tht crowd (amongst others) about two months ago as I was thinking the same as you.
They answered that they are not allowed to export GSM or CDMA amplifiers to Australia.
I think it might be that new "Free Trade Agreement and respecting our telcos" we now have with the US where things are not really "FREE".
Probabably if I asked 12 months ago it might not have been a problem.
Nice products.
Trouble with Antenna couplers , is that you lose at least 1.2db + in the cconnection.
You you really need a grunty antenna or output.
".. if you got carried away you could even connect your car to the ppc and moniter engine, fuel, etc. Plus a GPS.. and oh the possibilties are endless. "
Now I have an automatic car so rev monitoring would certainly be overkill.
I get your drift, though thanks for the input.
gregnash
I will have to see how much force is needed to engage the pda.
Don't forget that at least the same force will be needed to disengage it as well.
Mmmm...good point, this means seeing whether a panel mount socket is available in this cofig.
Wouldn't have a clue who might sell panel mount sockets suitable for the Harrier/Blue Angel?
I am not sure how a cable termination would cope with the forces needed.
The fixing method would have to be substantial.
Serial connections to the car comp?
You would probably need to hack the code to get access to it I suppose?
But if you could tap into the on-board engine management computer, then you could change the air to fuel ratio at the injectors and lots of other cool things like disengage my engine cut-out at 190k/per hour and have some real fun!!!
Not much fun at 190K/h and the engine stops-no brakes, no steer!!!
Must be for the rev heads-NOT ME!
I will investigate the force on the antenna connector to see if this is feasable to mount.
I will let you know what I find.
Hi all.
Thanks for the encouragement.
Well life is full of compromises!
So long as you do not require audio output and you are happy with the Harriers speakerphone volume, I think I have a home solution for the uninitiated.
1. I have a "generic brand mobile phone holder-one of those adjustable in width ones- full width just held the Harrier nice and snug.
2. To this I mounted at the bottom (after removing the locking latches)
a USB car charger cable -with no modifications.
-Actually I pop rivetted the backing shell to the holder.
3. I then mounted a Nokia a passive antenna coupler and sculptured the holder-so that it fits at the right height and to the left of the Harrier.(where the antennae is on the Harrier)
4. I then mounted the holder onto the dash of the car (my choice as I put it though a removable panel where a digital clock is fitted in an other model, and passed the antenna cable,and the charger cable to a cavity in the dash.
5. Here I supplied a cigarette socket with 12 volts and connected the charger cable.
What I ended up with was a car mount that was a "drop in" style that
was easy to build without any fiddly soldering of connector pins.
I actually did make it with USB and audio out but these were surperflous as at the moment I do not have an audio in for my car radio or an amp to drive it.
But I just wanted to see if it could be done.
This is why in the picture you can see electrical tape around the cabling.
(This is because I had USB,Audio out and Car charger cable.)
Once you have this type of holder, it is not hard to get a new holder and move only the antenna coupler across ( I would think that the new connector would be different from the Harrier)when you upgrade to a new PDA.
In summary:
Compromise 1.
1.2db loss at antenna coupler-using 9db external antennae so I can live with that.- but no nasty "push to connect" hassles.
Compromise 2.
Audio out does work but the level is so low that it needs good amplification , this I will not follow up until I get a car radio with audio in.
Rely on Speakerphone fore the time being.
I hope this is of help to those thinking of this kind of project.
I hope the picture is reasonably self explanitary.
If you have any questions just let me know.
Hi Guys,
I have just got the fantastic little E72 and it is great in almost every way. I want to be able to use my Shure headset with it so I need the adaptor that everyone else wants to find it seems. I have a HTC adaptor but it will not fit into the socket. The socket on my E72 has 5 pin holes and both sides of the interface are curved. The HTC adaptor has one curved side and a straight side so it will not fit in. The E72 does use the usb connection for its headset and audio output but when I did find a Samsung adaptor with both sides curved that did fit into the phone socket it still outputted the music to the external speaker so I am at a loss. There are, therefore, different types of mini usb connectors. Can someone tell me the exact spec of this one fitted to the E72 and possibly where I might get an adaptor that will work??
Much appreciate the help with this.
usb cant be changed to 3.5mm or any type of audio
the reason the htc one dont work is the same reason it dont fit
it have extre connectors which carry analog audio
normal miniusb is a serial digital interface which dont carry analog audio
and usb headsets for pc are really external audiocards which make the serial digital data to analog audio
and that require the ability to usbHost which few pda's support
Many thanks for the explanation. However, my phone came with a stereo headset with mic. I currently use this for listening to music but the quality is not good. Does this not mean then that I should be able to get analogue signal from it??
Please forgive my ignorance; I am learning!!
it all comes down to where you connect your headset
if it's the miniusb port benQ got an extention of miniUSB like htc's extusb
if it's a 2.5mm minijack like older htc devices used you can get a conveter to 3.5mm
The only port on the Benq E72 is the mini USB one. There are no other jacks. The problem is that both sides of the metal housing within this are curved so the HTC one (with one side of the miniUSB adaptor straight) wilkl not fit. I did manage to find and buy an adaptor that was branded Samsung and when I fitted it into the miniUSB socket on the phone it would not work. The music continued to play through the rear speaker even though the adaptor was connected. My supplied headset connects to the phone through the same miniUSB paor but again the metal housing of the miniUSB jack is curved at both sides. I hope this explains better.
as i said then miniUSb should not alow audio at all on the device
and htc use extusb which have more legs then miniusb so if it dont fit
it should not be because of any curves
does your benq device not alow headsets at all ?
if it does how are they connected?
The only connector on the Benq E72 is the miniUSB port. In the attached pic you will see the connector for the wired head set on the left and the miniUSB to standard USB for connection to the PC on the right. I looked inside the silver housing of the connectors on both cables and they seem to have 5 pins along the top (widest) part with the main section being hollow. Now the miniUSB housing on the actual phone does have a plastic inside with 5 pins and , I guess, more connectors along the top of this for the 2 cables. I am to assume that the plastic insert in the phone itsaelf is for the electric charger. There is nothing more that I can give you except to say again that the miniUSB is the only connector on the phone.
if it support headsets connected to the usb connector it must be using some sort
of special usb connector like htc's extusb
i would look at their site if they sell converters
Thanks, as I said the only way to connect the headset is by the miniUSB port so it must support audio. The issue is that the HTC miniUSb headset has a curved side and a straight side so it will not physically fit into the Benq E72 connector. I did get my hands on a philips miniUSB that did fit into the socket on my phone but the music still outputted to the rear speaker of the phone. So, my question is, is there different types of miniUSB wired internals? It would seem so. And would anyone know which would work for the Benq E72 windows mobile poweredsmartphone?
@ 17-apg,
Sorry for this off-topic post. Im planning to buy benq e72 because my o2 xphone2 is too old. Can you please give brief review of the phone, as a user. Is it true that it is laggish? Thank you.

No problem ,,
I have the device for over 2 months now and like it a lot. Had a HTC S730 before which was thick and cumbersome and I didnt really need the keyboard. This phone, in contrast, is very light and thin. It runs WinMo 6.0 and I do not find it slower than the HTC in any way. On reflection maybe a little faster even. It is very competively priced as it includes bluetooth, quad band radio and wi-fi. The bluetooth also carries the A2DP functionality. The screen, whilst a little small at 2" is very bright and clear. The keypad has large buttons and is very tactile and positive when texting.There's a 2 meg camera included as well as the microSD slot with a max size of 2GB. You can, however, with software, increase this to the norm of 6GB which I have done. Also the rear speaker (built in) is a reasonable size and therefore can play a decent sound for music if you are travelling and in a hotel room for example. And finally, it has little important assets like the ability to turn on auto redial, a button on the left side which when pressed and held will open the text messaging in a send window. There is also the facility to adjust the screen brightness as well as an internet radio and ringtone editor. All in all, for the price, I definitely recommend this phone. I have bought four more since for friends of mine. They paid of course!!! Now all I need is the miniUSB to 3.5mm audio jack sob sob...
Can you tell if a lanyard can be linked to the device - and where? On all available photos on the net I have not seen any holes for fitting the lanyard to :-(
I am really tempted to get that one as well - escpecially as it is the ONLY (!) smartphone with only a normal keyboard that can use microSDHC cards (after installing updated drivers). They seem to double in size every year - and if the standard is fully supported 6 or 8GB (as reported sucesfully) should not be the limit.
Lanyard
Yes, you can connect a lanyard at the top of the phone. If you can see the top view of the device there is a little hole there. You simply slide off the back cover and fit the lanyard to the designated area on the main body of the deivce (very easily) and then slide the back cover on again.
Now we just need a cooked 6.1 rom for the device!!!
Thanks - I found a set of pictures at a Taiwan Review site (http://www.eprice.com.tw/mobile/talk/?prod_id=2621&tid=3430647&page=1&list_page=1) - this tells it as well
I was only looking for a small device that can read memory cards > 4GB and this is the one now. Otherwise my Tornado in the house of a Robbie still perfectly fits my need. I also tried WM6 and WM6.1 on that - but fell back to the original WM5 there.
Just can't wait to get it in my hands - it was really a bargain on ebay. Search for benq E72 there and you will see a guy in London selling refurbished E72 for just 69 GBP (9 of 21 left). I just could not resist for that price, sigh...
BTW - on topic: did anyone try the Motorola mini-USB connectors - for the Razor and alike?
I dont think so. DO you habve one that you coulkd try when you get the phone? If so, let us know here cause I would really like to use my own ear buds.
BTW I think you will love this phone! It really impresses me. And also Expansys anre selling brand new ones for about £90.00!!
Is there a WM6.1 for this? Thanks.
Benq E72
Not thatI am aware of. I know that another avid fan of the E72 has requested ROM cookers to try to come up with the 6.1 version bit I am not sure if anyone has taken up the challenge.
I hope that it will happen soon ...
I have received mine in the meantime, but the refurbished one was delivered with a non-fitting headset :-(
Well, it fits mechanically, but there is no sound at all. It looks like a cheap replica of a Motorola Stereo Headset - but also a normal Motorola does not work in this socket. So I am out of any possibility to measure the data of the socket to build an adapter. I complained at the dealer - hopefully there still is a working headset available!
Otherwise the device is nice - only English language installed though for menus and T9.

With some help from Taiwan - the USB wiring for the headset is identified, see my blog article at http://tobbbie-benq-e72.blogspot.com/2008/12/hacking-usb-headset-connector.html for more details. The main information is:
....So the final result is then for the numbered pins of the USB connector (1-5):
Must be connected with a resistor less than 200 kOhms to ground (pin 5). The voltage will rise briefly to battery level but then drop back to 0,16 V to stay there. I suspect that accepting calls with the headset button will introduce new functionality here...
Speaker channel (l,r not checked, source indicates right here) - must be connected to a speaker or a pulldown resistor at device-headset connection time.
Speaker channel (l,r not checked, source indicates left here)
Microphone channel (checked to work with Audionotes)
Grounds
So luckily no complicated electronics - get your soldering irons ready!
BTW: have still not received the original headset :-(
