Car's computer inputs to nav screen, list of inputs?

[HB_G37S]

Hi all,

I am very new to the mod scene but have done a lot of android development and wanted to try my luck in creating my own "navigation" system based on android and wanted to use information supplied by the car's computer as input for some features. Would you know of any documentation that might be available that describes what format and the list of inputs? Are they serial or is it through something as simple as ethernet? Proprietary and not able to crack? I assume audio output is completely analog from the nav panel. Would be cool to tap into enviorn. controls and cameras as well.

Thanks!
