Finally find out how the car mode is triggerd
short circuit the ID Pin of the micro usb conector to any other pin will make my phone into Car mode and the car panel will popup if installed.
The ID-Pin is the 4th pin of the conector wich is the 2nd from left when desire facing up. Since the pc end of a data cable doesn't have the ID-pin, it won't work like this thread said

can someone confirm that
Can you confirm with pictures or diagrams?
So this means that an amended cable would do it every time?
yes, just like my car charger did, even when the charger is not pluged in the car lighter.
Can you please post pin-out schematics?
Thx.
i think the menu is hidden by htc as the desire does not have the copper pins at the bottom like the nexus 1. hence the nexus 1 car dock wont work on the desire. the nexus one can be charged with the pins and does not need the micro usb for car dock chargings / docking. i guess the car dock software options shown on the desire by accessing the settings widgets are a hangover from the similar software on the nexus 1 hence hidden on the desire by htc.
i have the car dock app installed (dont remember from where though) and it works fine instead with navigation / voice search icons etc.

HTC is coming out with their own car dock. That is why their 2.2 ROM has the necessary support for it.

something like that has been on th expansys and other websites since april / may onwards! so i wouldnt take that too seriously till it actually arrives and car dock works when docking.
at present i use the car dock app which has to be triggered manually but works fine. i use it with the car mode app.
Yesterday i was driving with the car charger inserted in the Desire, when i was moving the cable sometimes the Desire gave a little car icon and my NavApp was activated. Sow i think i has something to do with the 4th pin, and you don't need a certan resistor attatch to it to get it in a certain mode.

That is probably because it needs 2.2 to to work properly. That's why the timing just happens to be after the release of said ROM.
Seems very overpriced if all it does is hold and charge the phone + short some pins together to enable car mode. Seems like anyone could make something to do that.
I some how triggered car mode on my desire yesterday. It must have been as I inserted the charger as I pulled away so may have shorted a pin. but went to car doc mode and had car symbol on status bar and I had to push to exit even after unplugging charger. I have not been able to replicate this since.
I bought 3 mini usb to micro usb adapters from eBay to allow me to use my existing car chargers and all three of them put my Desire (2.2) into car mode but don't appear to work as data adapters in my quick test.
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=310237922332
I see the car symbol and the notification tells me that I am in car mode but what does it do for me?
Thanks,
Since Froyo update I keep getting the car icon in the task bar when I plug the charger in...
Following the instructions I've made a "car dock cable". I intend to use it with a usb car charger when that arrives. I just soldered pin 4 and 5 together, which now gives me the icon and navigator pop up.
I used one of these cables : http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=260636551302 as they have an easily removable micro usb end, plastic cover.
Can you give more details - 4 and 5 on the non Desire end?
Yes, more details please. Would be interesting if I can modify a Brodit active charger..

I also bought an active Brodit charger and it doesn't seem to trigger the car mode, so I am curious if it would be possible to modify to charger in order to achieve this.
Edit: I just sent an email to Brodit and asked them if its possible. Let's see what their answer will be. I post it asap.
I bought 2 different Mini usb to micro usb converters from Brando.hk.
Carmode triggered on both types when i use it with my old Athena charger.
think i paid around 6$ for a converter.
This might be easiest way without cutting cables and soldering.
theese are the converters.

Is anyone aware or the physical way to fool the desire to go into car dock mode either by rewiring a usb cable, or does it use the same magnetic sensor as the nexus, I currently use a boadit iPhone cradle that fits perfect and i have a charger mini usb cramped and srewed into the bottom, I would like to be just be able to drop it in and it go into the Navigator app and switch on bluetooth automaticly and kill both when i remove it ..

The droid/milestone used magnets to detect the dock, but the google car dock uses bluetooth and doesn't even use the usb cable (it uses the gold 3 bits on the bottom of the phone). I too wished you could do the same, but my brodit holder fit the phone so badly, I've decided to shell out and try the original car dock - just waiting for it to come.
Thanks for the reply, so the million dollar question is how does the desire's dock sense when its dropped in the cradle, any ideas people ? I read somewhere forgot now doh !! that it might be a case of grounding one of the data lines in the usb cable, can anyone confirm this ?
I'd like to know this too.. Dockmode/Cardockmode
Look at this thread - probably the id pin, but i need someone with the same charger and a multimeter to check some things
I have 2 chargers (work & home) that I use that plug directly into the wall, the one at home brings up Navigator where the one at work doesn't, so it must have to do with the pins in the USB connector.
Can you do some measurements with a multimeter on that charger that opens the navigator???
oh this sounds like what we wanna hear, my betting is one of the usb data lines gets grounded as ive mentioned before !!! plz test to see if more than one of the pins in the usb plu is being grounded .... pretty plz !! heh
Hey Guys,
yes it looks like the Desire can be fooled into thinking its connected to a car dock, my car charger seems to do it when the usb is not properly inserted.
I suspect HTC might release a car dock for the Desire. If not some one should really monopolise on the fact that this can be done.
I will be experimenting with it soon but currently have way to much uni work to finish for the end of the month
Ok went into the workshop and stripped the desire usb lead, I tried every combo of pulling the data lines to ground even both together, the installed navigator.apk didnt kick in , but looking at a reatime system dump i could see usbconnected and type(0) , type (1), type(2) had been triggered, on the differnt combo's i tested, why its not kicking in is anyones guess, maybe cas the Incredible navigator.apk is strictly configured for that device, guess the Incredibles navigators.apk has to be recompiled with new settings !!
I will try it with the cardock.apk tomorrow ripped from the nexus we might have more luck with that me thinks !!! fingers crossed !!!
Keep up the good work! I FINALLY get my Desire delivered tomorrow (after waiting 4.5weeks for stock!!!), so I can have a look at this too... let us know how you get on.
I'm interested in a homedock/multimediadock trigger as well as the car dock trigger. It should be included in the Desire as well as the cardock.
Here's an emulator that could be helpful in the process of developing a dockapp or finding out what's really happening..

I'll try to find the homedockingtrigger if there is any to use in my homemade dockstation

Same here! Any progress?!
after upgrade to froyo, i pluged my car charger in my desire and the car mode icon showed up, even when the other end of the charger is NOT pluged in the lighter. I use a charger for my old HTC Diamond and added a little thing that convert a mini USB port (wich is on diamond) to a micro USB. And the cable on my charger is too short for me so it has been moded (extended) by my self, there is only two wire in the cable for power, so there must be something in the plug itself that triggers the car mode. if only plug the converter into Desire, nothing happened
It's the ID pin that needs to be connected to ground, as indicated in this thread: http://forum.xda-developers.com/showthread.php?t=744636
So I'm searching and coming up somewhat empty handed.
Is it possible to engage Car Dock mode on the Evo via magnets, ala the Droid?
I'm also finding information regarding shorting pin 4 of the MicroUSB port to engage Car Dock Mode, but I'm also finding information saying that shorting pin 4 just tells the phone it's on a 'proper' USB charger.
So what's the deal? Do we even know how to engage Car Dock mode via hardware?
I believe HTC uses a 5th pin to let it know it's on a car dock.

USB Micro B calls for 5 pins -
Pin 1 is 5+, 5 is Signal ground
Pins 2 and 3 are Data+ and Data-
Pin 4 is listed as an 'ID' pin - if connected to ground, it's supposed to show a detection of 'Type A', if not grounded, then 'Type B'
I would think if pin 4 is utilized as 'grounded means 1000mAh charger vs USB's usual 500mAh' then how would the Evo differentiate between 'wall charger' and 'car dock'?
and the purpose of car dock mode and wanting to use it is.... ?????
You can manually launch the Car Panel from the launcher. Is there something else about dock mode that you're missing?

Nope, just wanting to know how the phone detects it should go into Car Dock mode.
Looks like nobody's sure how.
Hi, everyone:
I just got the HTC EVO car dock a few weeks ago, and I'm mostly pleased with it. One strange thing, though - it appears that the phone's battery will not charge as quickly as it used to, if it charges at all.
This evening, I tried an experiment. I had my 1A charger connected to the EVO dock, then I docked my EVO. When I go into Settings/About Phone/Status, Battery status shows Charging (USB). However, when I remove my phone from the dock and plug it into the charger directly, Battery status shows Charging (AC)!
I haven't been able to find an answer to this problem. One thread here stated it is a problem with Froyo and the dock application, that it only allows charging via USB, but I can't corroborate that. I found another thread that said it's a safety feature, that it won't charge a hot battery, but in my testing above, the battery is fairly cool and I still get different results.
Has anyone else come across this problem? Perhaps it's just a defective dock? Otherwise it's a fantastic car dock, but I'd hate to find out it has a design flaw that borks charging. Thanks!
The car dock does charge as usb mainly bc the dock has a slightly different pin set putting the phone into navigation mode ..but also decreasing contact with the port ...
Sent from my PC36100 using XDA App
I have the same car charging problem, although I don't use a dock, or the docking application. I just cannot charge in the car. The EVO reports that it is charging (AC), yet no electrons flow toward the phone from the car, as reported by both Current Widget and SnapTurbo's widget.
I've been looking for a solution to this issue for a while. The car's power port works fine. I can plug the home charger into an inverter and plug the inverter into the power port and that works perfectly. I have tried three different brands of car charger and none work. My next solution will be to find a DC12 to USB adapter and use my regular USB cable and see.
Hopefully we can get some answers.
OK, a little more info:
I installed CurrentWidget, and I logged my half-hour commute. For one log, I had the phone plugged in the Dock. For the other, I had my phone plugged in directly from the charger. For both sessions, I had 3G and GPS on, Car Home was running and I had the navigation program open. Here's what I found:
Phone in Dock average draw: -77.419Ma
Phone out of Dock average draw: +136.0588Ma
So, my unscientific conclusion is that the dock is somehow losing over 200Ma. With Nav, 3G and GPS running, that's enough to change the phone from a charging state to a dis-charging state.
I guess I'm going to return this dock. It's a shame, really, because otherwise it's a well-build, easy-to-use dock. But if it's not going to charge my phone while driving, it doesn't make sense to use.
It's not the dock, its froyo...when the dock is placed into dock mode by grounding pin 4 ANY dock that truly places the phone into dock mode will do it...I built a dock cable when the phone launched, it worked fine..now after froyo it and the HTC dock cause the usb only charging rate as well as the 3.5 jack volume fix..(won't go any louder)
It is the suck. I'm the OP on the HTC dock now available thread, I've had the thing a long time and had it apart, its power and ground with a jumper to ground pin 4..that's it..no data wires..that's also why it wont let u mount the usb...also the suck...hope that helps your problem..

Ok so heres my dilema... I am in the search of a car charger that could allow me to use my navi, pandora and be able to charge it at the same time in my car while using the verizon car mount.
It seems motorola quick charger seems to be the one to beat from what many people say in the forums. But i am looking to see if there is a adapter which would allow me to plug my own usb cord? The reason for that is so i can plug it in under the arm rest to keep it hidden and run a 6 foot micro usb cable to the mount. is this possible? I did it with my ip4 with out issues....
I tried a Kensington charger that seemed perfect (http://amzn.to/g3mBYU ), but it looses connection with the car (adapter is TIIIIINY) and when it does work, none of the ports can keep my phone (with verizon HTC dock) charged up while using my navigation and pandora. I was actually loosing power.
In another thread i just read just because it says itsd a certain voltage does not mean it would work since micro usb is limited....
Does anyone have a charger you can recommended? Or will i have to but a micro usb charger itself with the cord attached to it.
Part of me says i should just get the moto quick charger, but i dont think the cable will be long enough to keep it hidden and i would have to keep it plugged in in the front part of the car. If i can get a long cable i dont need to keep plugging, unplugging and ju st dump the whole mount in the armwrest when i am finished
Any help on this will be appreciated. ive been doing alot of google searches but everyone has mixed opinions on this.
Find one that can output 1A.
I did... The one i put onbthe web link in my original post...but it was not outputting enough juice.

Go on Amazon and search Motorola micro usb car charger. The OEM Shop sells one for like $5. 00. I've been using it for months and it's a real Moto charger and works great.

thats the same motoi was talking about on my original post. i actually went ahead and ordered it from amazon. its supposed to push 950mah should receive it very soon
I use the iGo charger with the HTC tip works really well and its a rapid charger. it should meet all your needs
The moto quick charger rocks. Not sure I understand why you cant run it from the plug to your dock? Coil cords are 6ft and will stretch out. Thats how I ran mine. I will probable post some pics later of my setup - works great.
Not sure if this is the right forum, but I'm making a custom car dock for my 05 Mazda 6.
The resistor value to kick it over to car dock is (This is using a Decade Box RS-200):
5-16 kOhms (4.939-16 kOhms from my meter resistor networks).
Haven't figured out if I can get audio through USB while in car dock. Seems playing with resistors and plugging/unplugging can get it stuck sending audio thorugh the D+/D- lines.
USB Audio (no car dock):
19-41 kOhms (24.6 kOhms from meter over resistor network)
Lite Dock Mode (no usb audio), effectively an alarm clock:
44-49 kOhms (44.4 kOhms from meter)
Install this between pins 4 and 5 of a micro usb connector (USB Cable will not work).
I'm going to get a surface mount component to reduce the size and integrate it into my card board mock-up of my car mount.
Updated with some new resistor values for other dock modes. Going to get a decade box and play some more with the values tomorrow.
Would def like to see more info and progress on this, seems to be very interesting.

What are you looking for? I'm sorta stuck against the wall with things to try regarding getting intermediate modes.
I am curious to know what happens in the kernel, if this is a Hardware Switch or if there is an A/D measuring the pin and the Software is selecting which function to control. If I only had the time to dig into the AndroidSDK and figure it out.
Lol, I don't know anything technical about it, I just understand about 60% what you are saying and doing, it's interesting, that's all, sorry I couldn't be of actual help
Hi, I've been trying to get this to work with my thunderbolt and I'm not having any luck. I've tried the car mode and desk mode resistor values and neither are detected by the phone as being a dock. I have a Seidio home dock that is basically just passthrough USB. I've tried different ROMs too to see if it's a software problem, but with SoaB 1.3, BAMF Forever, CM7.1.1, and stock none of them auto launch dock mode. Any ideas?
Nevermind... it was a dumb mistake by me. I didn't realize that the board that I was soldering on was on the receptacle side and not the plug that goes into the phone. I was soldering the resistor to a pin that wasn't being used at all. I cut open the phone end of the dock and soldered it there and it works great now.
Can you post some pictures?
Would this work for Incredible S?
Back in the days of my Nexus S I used this values: http://forum.xda-developers.com/showthread.php?t=820275
