Is there a car charger that has the usb shorted correctly so it can recognize car dock for tasker. I have the ATT one and it doesn't cause the phone to go into dock mode.

I thought dock modes were achieved with magnetic sensors? If it is based on a pin-out adjustment then a DIY should be easy.
I ended up setting tasker to turn on BT when plugged into power source and then look for a specific pairing. When it finds my stereo it launches the car dock app. After unplugging the powers source the BT turns off and the car app closes.

Hey how did you get tasker to connect to a specific pairing? I have a similar setup for streaming music but I always have to specifically pick it, I couldn't figure out how to make tasker find it.
I did research to find out the method the captivate uses. Magnetic or pin out. From what I can find its a pin out. I can't find a wiring diagram to show the exact pin out.

A quick "where is it" response, without detailing a profile build...
you can find it under the "State" section of the profile screen
1. launch Tasker
2. select "new"
3. create a new profile name and select "OK"
4. go down the list and select "State"
5. select "Bluetooth Connected"
6. enter the device name
Hope this helps. I seriously cant believe how awesome tasker makes this phone. It does what so many crap apps on the market do, but it does it for free!

There is no magnet sensor in the phone, so you would have to see the charger go to A/C versus USB.

That has baffled me for a few days. The normal wall chargers convert A/C to D/C for charging and USB ports always run on A/C. This leads me to believe that the data pins let the phone what type of connection it has. With 8 pins on the micro USB and no video output there has to be some extras used for something. I would be willing to DIY a dock cable if there were diagrams of the pin-out and docking was possible.

Yes, I and others have posted extensively about this - searching on car chargers should find some links - but basically:
First - all charging is 5V DC. The wall charger converts 120V AC to 5V DC - the USB port is 5V DC; Car chargers convert 12V DC to 5V DC. Next measurement is Amps - wall chargers supply about 700mA - USB is 500 mA. Many car chargers are 500mA some are 1Amp (1000mA).
The wall charger automatically connects the data pins so the phone knows it is on "AC" and charges faster.
The phone will limit the Amps it draws to about 700 - if you want your car charger to charger at maximum rate - you need to get a 1A charger and you need to short the data pins at micro usb end.
I bought a dual 1 amp car charger (2 1amp uSB ports - Griffin brand i think) and I took an extra USB cable, opened the wire near the micro usb end and connect the 2 data lines (black and red are power, the other 2 are data) together so they loop back at the micro USB end.
My phone now reads "AC charging" when plugged into my car. You will never get this on a PC USB port as it does not put out enough power.
But if I understand correctly it should know the difference between home dock and car dock.

Based on what Alphadog just posted the phone could determine if it is on a USB (pc/data) connection or an A/C connection. The outcome could vary depending on the specifics of the device being used to charge the phone but it comes down to the pin-out.
That being said, I was looking at some of the Tasker settings that could be used in this scenario. I was thinking for those who do not have BT that other triggers could be used. A good trigger for docking could use combos such as "power" and "orientation" or "power" and "location".
A second thought had me wondering about the compass. I have not looked into this but I don't see why you couldn't utilize the compass as a sort of magnetic sensor. If for example we told tasker to look for a specific scenario such as:
1. Receiving ac/usb power
2. Phone in Left Horizontal orientation
3. "Compass sensor north" pulling towards orientated left
Tasker would then launch Desk Dock.
....I know, Tasker does not have settings for current compass sensor direction. but could a specifically written app do this?
I currently use orientation and power for mine.

I have the car charger you can buy at att. It has a usb port I'll have to try it with the usb cable that came with the phone. If that works then I could have saved alot of money buy just buying a generic plug with usb
dont bother with tasker there is an app for that
use DockCarSwitches to turn bluetooth on when docked in car(car charger)
use Bluetooth Application Launcher to launch your application(Car Doc application for example) when a particular bluetooth device is paired
This Samsung car dock both charges your phone and activates the car home app.

I think you misunderstand the point of Tasker.
To get USB/AC under Settings / About Phone / Status from a USB Car Plug, you need 2 things: 1) A Car Plug with enough Amps (I use a model that has up to 2100mA in a single USB socket. Even runs & charges Android Tablets at same time) 2) a correctly wired USB to microUSB cable. (same place that sells the high power USB plug has this cable)
When I use these two together with my Captivate, it charges very quickly.
By the way, both Gigabit and Asrock motherboards are shipping motherboards with Always on, high power, USB ports.

That's incorrect. Unless, the dock the OP uses requires it somehow. It's much easier to short the Data connectors on the larger end of a standard USB to Micro USB cable to trigger the phone for AC Charging. It takes less than 2 minutes and requires no wire splicing. Linky

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.
Sent from my MB860 using Tapatalk
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.

I plan to fit a desktop cradle in my car and I'd like to wire the Xperia audio output to my car stereo. Is it possible to use the micro-usb connector for both power and audio output? I've found a few threads on the Samsung forum showing how to do this on a Galaxy. Is the wiring the same on the Xperia and would I need to use the resistor trick to get the audio via the micro-usb connector? http://forum.xda-developers.com/showthread.php?t=1321491
AFAIK if your car stereo reads USB then plug in and mount sdcard that way you can view file on the stereo itself and it will be charging, if not then use AUX lead with micro USB

I'll also be interested in so... and wayne, is not the same, for example, I listened music via spotify, so I cannot listened to it if only connecting through usb mounted sd card...
Otherwise, anyone know how to enable dock mode or car mode connecting in the arc?
you'll need to use the headphone output. or bluetooth.
Unfortunately my car doesn't have a USB connection. I wanted to use the car stereo's aux audio input. So can any one confirm that the Xperia definitely can't output audio via the micro usb?
Is your car aux connection a USB? Or is it a 3.5mm connection like my car? If so you can get a 3.5mm male to male lead from Ebay

Yes it is 3.5mm but I don't want to use the 3.5mm socket. I want to be able to drop it into a desktop dock and connect both audio and power via the micro-usb. The dock will be sitting in a recessed part of the dash and there isn't room to drop the phone in to the dock with a 3.5 mm plug attached (even a right angled one).

Thanks good find
So I am planning on getting the Infuse dock for my S3. I want to hard-wire it in my truck so it is a clean install and wires are not everywhere. My options that I see right now are to splice in a cig lighter socket to the current one or the head unit power and then just plug in the car charger to that and run the wire behind the dash up to the mount.
I am assuming the power adapter that gets plugged into the cig lighter steps the power down from the 12v+ to the 3 or 4v to charge the phone correct? Or is this built into the part of the actual dock/mount that slides into the phone? If this is built into the dock/mount I could just run a wire straight down to the fuse panel and wire it in there without having to use a cig socket and adapter.
And another quick question....if I got a new head unit with a rear USB port I could just run a longer USB cable from the dock behind the dash to the rear input. Assuming this provides power, I could charge, use MTP, and stream pandora correct? Would this also replace Bluetooth hands free calling? I guess it would just be simple to pop the phone in the dock and have all those features and not have to worry about turning Bluetooth on and off and pairing. Plus I would assume audio quality would be better via a wired connection rather than Bluetooth.
Anyone?

The dock needs a micro usb connection, which is 5 volts. You have lots of options, from just plugging a micro usb car charger into the dock and lighter socket, to opening up that car charger and wiring direct to fuse box, to wiring a new lighter socket under the dash to the fuse box then getting the little adapter that looks like a rocket that plugs into a lighter socket and gives you a usb port. Combine that with a micro usb cable and poof. I did this last setup and it works great...
I'm considering upgrading from my Galaxy S (with voodoo sound and wolfson chip) to Galaxy S3. I'm on Bell. I understand that north-american version does not have wolfson chip and audio is worse than original S with voodoo. I use it for relatively high-quality aftermarket car audio using analog out to audio aux-in.
What are my options for S3? What's the cheapest usb dac I can use with north-american s3 and where to get it in Canada or US online?
Is there any guide about how to set it up?
Thanks!
Note: I reposted it to Q&A where it's more appropriate, but can't find how to delete it here...
it doesn't have the same sound chip???!!? what the hell.. deal breaker! is this true?

No wolfson chip for NA version hopefully we get Voodoo kernel soon. Until then, some people have had success using a Fiio e7 plugged into their S3 using USB OTG. As for how they did it, I have no clue.

I did some research on this. Apparently it's possible to plug in a whole bunch of USB OTG devices, including many USB DACs. However as USB port is occupied - they suck power from the phone and phone itself cannot be charged at the same time. There are cables that you can inject USB power but in Galaxy S3 case - only to devices, the phone itself switches to "give power" mode when working in USB ORG mode and does not accept charge over USB. This is a bummer, as there is no way it can hold a battery for long while playing music and working as GPS in a car.
There is a guy on another forum who mentioned that it's possible to force S3 to accept charge with change in kernel (that means it won't power other USB devices, but they can be powered via injected power), but this is beyond my ability. We need somebody who knows how to do this to either build an app, or do a kernel version (semaphore?) or both, that have this module disabled on demand.
Here's what he said:
" However, I was able to modify this kernel to make it accept a charge while in OTG host mode. A Y-cable is connecting my phone to a powered USB hub. The hub has a USB-to-Ethernet dongle, connected to a router. The hub is also powering the Gnex via the other end of the Y-cable. The phone can now, say, act as a WiFi access point (wired + 3G!) and it's battery level will never drop below 100% or 99%. One disadvantage: in a real on-the-go situation, this kernel will not anymore power slave devices. One could fix this by allowing the user to switch between OTG host mode charge-out (default) vs. OTG host mode charge-in."
" On the Galaxy Nexus, removing the complete body of method tuna_set_vbus_drive() in arch/arm/mach-omap2/board-tuna-connector.c will disable charging of OTG slave devices and will allow the OTG host itself to be charged. The battery icon will not be updated by this modification alone."
SUCCESS!!! I can confirm that this USB OTG cable (http://ebayitem.com/190710044655) DOES CHARGE MY GALAXY S3! I plugged in USB cardreader with SD card into the phone through this cable (it lit up and card is fully readable), then plugged USB cable end into PC and phone showed a charging icon! Moreover, after waiting for 5 min. with screen off (cardreader still glowing blue and working) battery has gone up from %72 to %75 (and while I was writing this, to 78%), so it is indeed charging! Yay! It probably won't get up in the car, where just phone alone is "not discharging" at best from the car adapter, but at least it should allow me to listen to music with quality DAC and use navigation without (or with minimal) discharging.
I have not tested it with USB DAC that I intend to use for my car (Behringer UCA222), because I have to go out and buy it. Hopefully it works. Anyway, this cable definitely works with simultaneously charging my north-american Samsung Galaxy S3 (from Bell Canada) while powering USB cardreader!
Somebody else has mentioned that another cable (http://ebayitem.com/120980364117) also worked in his Galaxy S2.

Sorry for double post, I posted it by mistake and can't delete the post. Button says "edit/delete" but there is no delete option, just edit...
I bought Behringer UCA222 USB DAC and tested it in my car with the USB OTG cable with power that I mentioned. It works great! And the phone is indicating a charge. Sometimes when first playing music after plugging the device it sounds like fast forward for a few seconds (I guess clock rate mismatch or something similar), but after the presumably clock is locked it plays perfectly fine.
There is a big list of working DACs in the official sound quality thread, along with a lot of other good information.
midirt,
I am working on a car setup like this and would like to ask a question. Somewhere I read that you had to plug microUSB into phone before plugging into DAC in order for it to work. Is this true for you? It would be a pain to have to unplug everything each time you get in car.

Usually I just plug entire setup into the phone and it works fine. Sometimes when I shut off the engine and start it up (there is power interruption) I have to re-plug the DAC.

Yes. Very good DAC, sounds great, and cheap. It's not perfect though: there is definitely a "dirty ground" noise when power is connected - it may not be its fault, I'm using a weird aux-in adapter and all other solutions I tried had the same problem, even phone itself, when connected to power supply. Disconnecting power supply there is no noise. It' not usually noticeable in the car, but it's there and I don't like it. If your car doesn't have noise when phone is connected directly to aux-in and plugged into power, this unit won't have that noise. I just wish they would separate ground or cleaned the power or did something to isolate noisy USB power, but it's too cheap to have that. Nor sure expensive ones can do this either. Ground-lifting transformer from ebay removes the noise, but also reduces quality so I'm not using it.
Another issue is sometimes in the beginning the sound just accelerated and is played fast-forward for a few seconds, then it catches up and plays normal. After that it works OK until restarted. Very weird and a bit annoying but not a deal killer.
