[Galaxy S III Android Development] walkeryan:
j0ep0 and I are currently working to get the mirroring that we were promised working with Drivelink and the Galaxy S III. Currently we have mirroring working successfully but there are a few bugs with the Drivelink app getting wiped and restarted. Here is a list of everything so far:

Full Mirroring without the drive link app resurfacing - Working (random restarts due to memory cleanup in android)

Work with Any Launcher - Currently Nova and Apex work

Reassigning the Home button -

Bypassing the two warning Messages -

Compatibility with Non-touchwiz Roms-

Compatibility with Other Devices -

Dim or turn off Phone screen when mirroring-

Automatically go into launcher (minimizing drivelink) -

Currently the setup we have is working for the following devices:

GSM Galaxy S III

CDMA Galaxy S III (No Data)

If it is working on your device please post, or PM me with the Following:

Carrier

Phone Model

Any Bugs

Rom/Kernel (If custom)

Installation Instructions:

Non-root:
Go into Settings and Enable "Install from Unknown sources"
Install the APK and run it.
Plug into your head unit and pray.
This method has worked for some (including myself) and not for others.
It will give you the standard Drivelink app and
no custom code by us, you need root for that.

Rooted users:
Download the TMServer zip to your Phone
Reboot into recovery and install (Like a ROM)
No need to wipe anything, you're just replacing
a system APK which is why you need root.
Install the Drivelink APK after enabling Unknown sources.
Run the Drivelink app and plug your phone into the head unit,
After accepting prompts you should see the drive link app.

There are several ways to get to your stock home screen but the easiest for me is to hold your home button down the bring up task manager, Click on another open app, when it opens hit the home button and viola, you're at your home screen. We are trying to find a way to bypass this but drivelink puts the phone into car mode and that disables the home button. Car mode is required to get the audio to route correctly to the head unit.

Here are the Links:

TM Server- Must be flashed in a custom recovery:

TMServer

Drivelink- Remove all versions, allow unknown sources and install this apk:

DriveLink

Both j0ep0 and myself have full time jobs and families so we are working very hard to get this working on our own time. So please be patient. We will get this working fully!

Nice description write up by Olywa123, Thanks

What is it

Drivelink is Samsung's application used to facilitate ‘Mirrorlink’ connectivity with supported car headunits. Currently their are several aftermarket car stereos by Sony, Alpine, and JVC that support this technology. The majority of users here have the Sony XAV-601BT headunit but it is believed the protocol for connection is the same for each. This standard is known as Mirrorlink (formerly Terminal Mode) and uses the VNC RFB3.8 protocol allowing for two-way communication between the smartphone and headunit over a usb connection for both display duplication and key-inputs and uses Bluetooth A2DP for Audio.

The following videos best provide a summary of this technology

Why The Drive Link App needs Modification

Although Samsung have released the Drivelink application, this is not only very limited but also compatible only with the Galaxy SIII currently. It provides a ‘dashboard’ interface allowing for the use of only stock Music, Phone and Navigation (limited to Google maps) functionality. You cannot get back to your phones home screen or run any other apps while Drivelink is running/mirrored on the headunit and killing Drivelink kills the interface meaning the stereo no longer sees and mirrors the phones display. This appears to be a restriction coded into the Drivelink software as the video above shows that the Nokia interface allows for full phone control in addition to just the Nokia released Mirrorlink app on Symbian (Car Mode).
