UPDATE:Excellent. I'm going to give it a try for my '08 CCC iDrive with the appropriate Xcarlink. But instead of your Android TV box I'm going to try this Android 5.2 Quad Core stick which is much smaller:
Tops CX919 Quad Core TV Stick Google Android 5.1 2G/8GB Bluetooth 1080P with External WiFi Antenna XBMC DLNA

I also plan to mirror my iPhone screen into the second AV input on the Xcarlink (hopefully to get both Waze and MHD together on split screens). I have an iPhone 6+ mounted via the CD slot above the shifter for Waze, etc., I plan to connect it to an Apple Lightning Digital AV (HDMI) Adapter (poking out from the ashtray area, which is also connected to a Lightning cable for charging ) --> HDMI cable --> HDMI/RCA converter --> Xcarlink AV2 and audio back to AuxIn.
And finally add a backup camera too.
UPDATE:
The Tops CX919 Quad Core TV Stick Google Android 5.1 proved to be unreliable (flimsy) and slow. Boot times were more than a minute because it loaded a large media front app (it's a TV stick afterall). I then tried another very basic Android Mini PC and while it was much quicker in day 1, by day 2 it wasn't stable, crashed, and required multiple reboots. Still looking for a quick Android Mini PC.
@doublespaces How did yours work out?
I have to try this.
I will definitely hit you up when I get all the parts together. thanksLet me know if you need any help installing or setting it up to switch to auto logging.
There's also a company in Australia that'll switch out the CCC or CIC display with a touchscreen and add Android directly for $900AUD. www.advancedice.com.au
I checked with them and it's still available. Too late for me as I already purchased the video interface.
doublespaces, fantastic work! Thanks for the info! how are you getting MHD to auto start logging? are you using a 3rd party app like tasker?
For what its worth Ive been working on a similar project before I came across this thread . I'm near finished and will do a write up with pics soon. My install has a bunch of added functionality and features that I think you guys will love...
