Vehicle dock charging cable.

I've just watched this video...
http://youtube/fCBFdNMhCCw
If you look at the charging cable for it, it has a 3.5mm headphone jack (so that it can be plugged into the aux in on a stereo)
Is there any way to buy just this cable so we can have audio over usb? Or even a way to hack one together DIY style?
Thanks.

Have you tried plugging usb in from the charging cable to see if you can put into mass storage mode and read files like a thumb drive? I would check that first.

That would probably work but I just have never seen a cable with the 3.5mm jack built in. I don't have my atrix yet, just doing some research into different things.
Should have it by late next week

Yeah, just so there's one cable coming down for charging and audio aux. Unfortunately, I don't see a way for a stereo or processor to read the phone properly until Harman's Google Open Protocol project gets into the market.

I have the dock/cable
One cable goes into the dock which the usb on the phone plugs into.
The HP jack comes out of the other end to connect to the AUX input in the car.
There are two labels on the cable, one says not to plug directly into the phone on the mini usb end and the other says not to plug into a PC (both in pictures)

I have the car dock and the usb cable supplied with the 3.5 mm does not work as a sync cable.

It's a dock dependent cable. Great question and perhaps abthird party will step up and manufacture a micro USB charging/ audio combo cable that can be used without seperate dock. Alternatively, contact your local rocket scientist. Lol! Actually, the multimedia dock does exactly the same thing, presenting an audio out jack.

But in the multimedia dock, I would assume that audio is coming through HDMI. This dock is much different than laptop dock and multimedia dock just because it conencts with phone only over USB but still gives an audio plug at the other end.
Also, I would assume that audio streaming is built into the cable and not in the dock because cable connecting to the dock is just a USB connector.
Now if audio is flowing through USB cable, the only question is if it can be played without using accompanied 3.5 mm audio jack?
To get to bottom of this question, it would require some USB debugging expertise which I dont have. Can anyone check with devs in forum?

There is no way audio is coming through HDMI because there is no HDMI port.
The car dock does something with the atrix where the atrix turns the USB port into analogue audio out/power. It's pretty much replacing data with audio out.
It specifically says on the cable to not plug into a computer, because the wires do not go where they are normally supposed to go (since it splits)

I have no reason to believe that the multimedia dock (not to be confused with the HD dock) and the car dock are any different in how the micro USB connector interacts with the phone. One thing that we do know is that the micro USB connector on the car dock is expecting a special cable. It literally states not to connect the car dock wire directly to the phone. Anyway, the bottom line is why does it matter, the key is that Moto engineered a product that will charge and output audio using a single connector. The car dock wire has the 3.5 mm audio out. The multimedia dock has the 3.5 mm audio out on the back... All appears to be the same to me. One thing worth noting is that the multimedia dock will not interface with a PC. I read a post that described the connection type, but can't remember what it was.

Im not sure how the he dock works, but the webtop hack has sound. If the he dock is just webtop/hd sharing, then yes, its hdmi. Charging via the usb port. But I don't own those docks, only the car dock, so im not sure.

The HDMI port is for video with audio only and used for the HD dock, lap dock and webtop hack. The micro USB port is used by the HD dock and lapdock to provide USB hub like functionality to the dock as well as a mechanism for charging the phone. This USB hub like functionality is the basis for the lapdock keyboard/track pad and HD dock wired USB keyboard and mouse. A Bluetooth keyboard/mouse can be substituted I believe, connecting via the phone's built in Bluetooth. The multimedia dock and car dock do not provide computer USB type connection capabilities, and NO video capabilites, as the HDMI connection is abscent. Instead they will charge the phone AND provide connectivity for analog audio out and that is it. The webtop hack is just a way of activating HDMIfeatures that are normally only triggered in the HD dock or lapdock.

Yes... I knew all of that... just too lazy to type that...
so... that doesn't really lead us anywhere?
I don't think you can use the vehicle dock cable with the phone directly unless someone reverse engineers the car dock.

Yeah, I guesses you probably did, but then a noob comes along and decides 1+1=8.

can micro usb send audio out ?

For my in car solution, previously I used a brodit Active dock which you could plug an iphone cable into the bottom of, that cable I used previously for iphone was one iphone port in, but had an audio out as well as usb charge cable, so I was able to jack into my cars 3.5 Audio port and the other end into a usb cigarette port adapter, it was commonly referred to as a Y Cable.
I am looking to do similar from the Brodit Active HTC One X dock once its released, and ideally use one cable that plugs into the docks micro usb port (which the HTC One X plugs into in the dock).
So, a) does the micro usb port on the phone support sending the audio out ? and b) if so, does anyone know of a cable that will split out to an audio and usb end such as I described above..
Thanks for any help anyone can offer.

to give some context, I used a cable like this one for the iphone and active brodit dock before..

I cannot seem to find anything similar for micro usb.

The USB does HDMI which carries audio. Someone with more knowledge will be along soon I imagine though, they'll be able to point you where you need to be!

thanks for the hdmi headsup.
Anyone else able to offer a solution ?

HDMI is digital though, so to use with a standard 3.5mm Aux you will need a digital to analogue converter. Assuming it cant switch to analogue... its a bit up in the air at the moment, need to wait for a few devices to hit the shops :/

All you need is-
Micro Sd to car adaptor for power.
3.5 jack to 3.5 from phone to stereos aux in.
You can call, use sat nav whilst listening to music.
Will mute music for ditections, phone call whateva!

You can also make a cable and connect them to the pins on the back that are used for a dock.

Thanks for the replies. I already have two separate cables wires in for aux and for usb, but I wanted to try and have only one cable so I could literally attach one and not have to plug both in and out, hence the year cable idea of

Using USB as audio output?

Hi everyone
I know this has been posted in another forums, but without any or good answer.
What i want it's to make an USB to 3.5 Jack adapter to use with my Galaxy S2.
Anyone can help me with this? I'm curretly using RR and as far i could read it says it doesn't have the Dock mode. So, this will be possible?
Thanks for the help!

pinouts

These are the pinouts for the micro USB with instructions on how to make the cable. You can ignore the power input unless you are trying to make a nifty car dock...
Sorry I don't know about dock mode, but different ROMS behave way differently on the USB, so I would try ROMs and kernels until it works. I think ICS is better for USB connecting things.
Good luck.

Tried on RR 2.4 with Samsung Desktop Dock using line out from the dock to speakers - doesn't work.
Was hopeful because I saw Dock audio settings under System Settings --> Dock, but Audio options was greyed out. Likely to be an issue with CM9 and Siyah kernals.

i've gone about it in a different way. i'm fitting a usb port to a blanking cover in my dash board and taking a aux line in from my head unit and power from behind the dash (ignition fed). as i have an s3 i need 1 amp for the power side of things. all parts have come from ebay for about £11.00 about $18.00

Nice work Post pics/detailed instructions. I'm sure other people will be very interested.

Audio Out / Charge micro USB cable

Hi there,
I'm looking at returning back to the Android scene with a nice shiny new S3 after being over on the dark side with my iPhone (I know I know!!!). However, I do love one of the things I can do with my iPhone which is listen to my music in the car via the port at the bottom by using a Y cable which splits the output into a USB plug (for charging) and a 3.5mm Jack for AUX in sound.
Does the S3 offer music output and charging via the micro USB slot at the bottom? Has anyone tried this? I've done numerous search's and keep coming up short, with the exception of a post on here that shows the amendment of an iPhone Y cable into a Micro USB version, but that was for the S2.

If your interested in a car dock the Samsung infuse dock works for a single dock connection, but of course the dock has a charger and audio lead.

Hmm, worth thinking about! It's the all in one solution I'm after, so this might work.
Any idea if Samsung are going to bring an official dock for the s3?

We are all looking but the only thing official so far was a cradle (no connections). Speculation was perhaps an inductive charging dock but?..

The microusb does support outputting audio+taking in power.
I haven't seen a cheap cable for that purpose but just made one myself in the end from an old usb cable, an audio cable and a 690K resistor.
A y-cable made for the S2 should work fine on the S3 (that is what I based my cable on)
Ebay will probably have something suitable

Thanks for that, any write up on how it's done? What's the sound quality like please?

I will be constructing and selling around 10 of these cables (Micro USB to audio out+charging). Please PM or email me on [email protected] if interested.

Thanks for that, did my own and works a treat!! happy days.
Now if I can just stop S-Voice auto loading when it's plugged in!!!!!

Combined audio/charging cable for Note 10.1 N8010?

Hello all, I've been searching this one now for a few hours and wondering if such a cable exists, surely it must do?
I am making a custom car dock for my Note 10.1 N8010 (2012 version) and would like a cable that allows it to charge (at the full 2 amps, I've got a car charger, the cable just needs a USB A plug to go into it) and also output audio through the dock connector. An OTG port for plugging in external storage would also be nice but not essential. Does such a cable exist? I don't mind if the audio side is RCA or 3.5mm jack, I can convert it to what I need.
The closest I could find is this one on Alibaba: http://www.alibaba.com/product-detail/USB-AV-Audio-Video-TV-Out_60008986653.html but it says it's only compatible with the Tab 7" and has a minimum order quantity of 20 units, I only need one! There's so many cables out there for newer models but I can't seem to find one at all for the 2012 version.
Another possible solution might be something like this: http://www.amazon.com/Zek-Samsung-Galaxy-Reader-Adapter/dp/B00DZA6F74 , which, although powered, doesn't specifically say that it could charge the tablet (says it's to power connected accessories). Does anyone have any experience with something like this?
Can anyone else advise on this? As a last resort I could cannibalise one of the many cheap docks on ebay but I'd much rather use a cable for a neater result. Ideally my budget would be under £10 but I'd consider up to £25 as an absolute maximum.

I own it & the external power is not for charging.
It's for powering a high powered USB devices such as USB HDD.

Thanks for letting me know. Makes sense, I'm just surprised that no cable exists for charging and audio output at the same time along with OTG, I'm sure it must be possible somehow. I guess I'm just asking it to do too much, I may go for the video output cable from Alibaba in that case then and do without the OTG/USB functions.

There's a dock that has charging and a seperate audio (analog) output. I have two of them. The audio only works with stock Samsung roms though. With CM there's no audio out.
