I'm using an adjustable car mount from proclip that holds my phone really nicely in my truck, and I've got a 1000mA USB car adapter that charges the phone really well with a standard USB cable.
My question is about getting the phone to go into car mode when I plug it in. I've read some posts that say shorting the data pins together in the USB cable will make the phone see it as a car charger. Has anyone had any luck making a cable like this? Does it work? Is there anywhere where I can buy one for cheap?
I believe that you can set a profile in Tasker to have car mode enabled whenever AC, USB or both are present.

I've made a cable that does this. I had to buy parts in bulk so I'm listing the rest of them in the XDA market: http://forum.xda-developers.com/showthread.php?t=784379.
@Davpel - That might work, but then wouldn't it go into car mode whenever I plugged it in elsewhere too?
@ForceO - Sounds nice, but I can't get into the market... I don't think I have enough posts yet. Can you PM me the info?
Using tasker to run car mode will not run car mode every time you plug your phone into a usb charger, if you download the power plug profile from the tasker wiki and install it. When you plug your phone, your phone will ask you if you want car, home or night mode. Pick car mode and tasker will run whatever car dock program you want. I use Custom car home.

ForceOnature has the ticket, that's it, ground pin 4 on the micro usb.

It's pretty easy to make, just take a grinder to a micro usb cable, then pick the extra plastic off with your fingers, then solder a jumper between pins 4 and 5, that part can be tricky because of the size of the tab you need to solder to....patience is key.

I tried the Dremel route and it was definitely not easy. Ended up having to abort and make my own from scratch because the plastic/epoxy stuff used to fill in under the black rubber shell was too hard to remove and still leave the pins intact.
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

I'm sure someone could post the apk for us to download. Or send it to me and I can host it for free on a site of mine... the perks of working for a web hosting company.
I have bought myself a car mount for my phone, but what I would like to know is, What actually activates car dock mode on this phone? Some people said their should by a small magnet in the holder that activates a mag switch in the phone? Is that true or should I go into car dock mode manually every time?
it's true "their should by a small magnet..."
According to this page it is the USB cord that activates the car dock mode. It probably has some resistors from a pin to another pin, so that your device knows when to change to dock mode.
The fifth pin is grounded in the charger (actually this is the wiring in type A micro USB plugs, but with the form factor of type B micro USB). The better alternative is to use Google's car panel - you can set it to open itself when connected to your bluetooth handfree, you can have any navigation software launched by it and best of all - it works in landscape (a huge oversight on HTC's part).

nice to know
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.

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.

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.
