Thanks for the info. The board has arrived today, it was cheap so I figured I'd give it a go and see if I can get anything. I'll have a good look into the wiring tomorrow and see if I can get any results.

Well I decided I couldn't wait until the morning so I went and had a play. I do have a TV module so I've used the RGBS out from that. as you can see I've got a full image I just need to adjust the colour levels on the converter board and then hopefully it'll be perfect. It was a bit fiddly in the dark with patch wires pushed into the connector so I'll wire it properly in the morning but for now I'm pretty happy with the results!js_online said:
I've ordered the screen i'll be using as well as the other bits and pieces however with the screen coming from china it could be quite a while before I get to complete it

Looks good. TV tuner simplified solution, but on another hand LM1881 is also not big deal.
Access to MK4 in E46 looks super easy. To get access to MK4 in Z4 I should remove all center console
Good luck with completion of you project. Please share final results later.

Here's the results (copied from another forum) - Android integration into the OEM nav screen. Basically I wanted and android head unit whilst also keeping the cars original interface and menus. This way I could keep the use of my intravee, the cars radio and bluetooth which is much better quality than those in the android head units.
I started out by researching what video signal is provided to the OEM board monitor which turned out to be RGB which I could access from the TV module. As my intention was to replace the LCD in the board monitor with a higher resolution panel with touchscreen I would need to convert this to VGA. In order to do this a converter board would be required so I sourced one to test before committing to ordering the other components.
I had to make an interface cable to connect the RGB siganal to the converter board which can be seen below and as you can see this was a success!
Once I'd got the video signal converted I worked out the basic layout of what components would be needed and how everything would connect up
I decided to use an Odroid C2 as the android device as it seemed quite customisable and sufficiently powerful for the application. I found the 6.5" screen with driver and touch overlay on eBay.
As the screen was coming from china this gave me plenty of time to work out the exact wiring required and where everything would connect:
Once everything had arrived I started by removing the boot carpet and routing the wiring through, HDMI for android, VGA for the MK4 Nav, one composite for the reverse camera and the other as the trigger wire and then the USB for the touch screen:
I set about disassembling the board monitor and adapting it for the new screen. As the CD drive in it would not longer be usable I decided to rewire the eject button to act as the input change on the new screen allowing me to switch between the VGA and HDMI. I also installed the Infra red receiver for the screens remote in place of the light sensor in case I wanted to make alterations to the screens settings:
Once I'd completed the screen it was just a case of setting up android and enabling USB touchscreen support on the Odroid C2. I've now got fully functional android as well as the original car systems which looks completely OEM from inside. I've also got the use of 'OK Google' enabling me to use my voice to play music and navigate etc. Here's a quick video of it in action:
I'm really pleased with how it's turned out, what do you guys think?

Hi there I am in the last part of the project I got the arduino board....
Unfortunately I can't see any pictures of the wiringredients steps in the forum. And is the first time I try to use this board. So I would appreciate some help with the wiring.
Thank you in advance for your time.

Sony Xperia ZU AutoBoot on Power
Idea is to turn off phone if not on power and not used for a long time (for example 4hours). Autoboot after ignition is turned on (charger connected).
Turn off functionality can be achieved by Tasker app Timer and Secure Settings Reboot functionality. But powering automatically on requires additional effort.
After spending some time on this task sharing results.
Problem: after connecting power to phone chargemon starts (animation with battery) and is not allowing to complete booting. Booting continues after pressing and holding power button
Expectation Boot completely after charger is connected (ignition is turned on).
I have dualrecovery installed on my phone. I am running ZU-lockeddualrecovery2.8.26-RELEASE.combined. Readmore here.
How to enable autoboot? (do only if you understand fully, this is on your own responsibility)
1. Do backup of /system/bin/dualrecovery.sh (for example copy to SDCard1 - this is external SDCard of phone and rename to dualrecovery.sh.backup). I use SSH Droid app to connect using WinSCP to phone.
2. Copy dualrecovery.sh to computer and edit (in WinSCP or Unix Editor) to comment out by adding # in front of line 483 (# exec /system/bin/chargemon.stock)
3. Save changes and copy file back to SDCard1 (this is external SD Card of phone)
4. Boot in TWRP
5. Mount System: Mount, click System to enable checkbox
6. Open Advanced --> File Manager and copy modified dualrecovery.sh file from SDCard1 to /system/bin/
7. Go to /system/bin/ and apply chmod 755 to dualrecovery.sh (hold long on filename + select CHMOD 755)
8. Unmount System: Mount, click System to remove checkbox
9. Exit TWRP --> Reboot, Power Off
10. Test. Connect charger, phone will boot fully
In case of issues (phone is not booting etc.) enter TWRP. Rename and copy original file back in the same way.

hi everybody, I read this forum for weeks now... Do you think this can work on my mk4 integrated business DVD CD radio? http://www.ebay.fr/itm/AUX-IN-Adapt...MEBIDX:IT&_trksid=p2060353.m1438.l2649[i][/i]
because I don't want to drill a hole to pass an USB cable through the dashboard... :driving:
