I've been trying to mess around in the touch screen android system for couple days trying to figure out a way to install apps like Waze and any app for the matter of fact.
I went into the diagnostic menu (holding the power + brightness button + menu) i think, tapping the bottom option and holding "menu" again for a couple seconds.
Long story short, when i start my car, both screens turn on but nothing is displayed afterwards. On the top screen, Lanewatch + backup camera? works, but nothing else, screen is blank otherwise. & on the bottom screen, the startup animation comes on then screen goes blank.
I've tried removing the negative battery terminal for 10-20mins hoping it would reset anything thats wrong but having the same problem. I've held down the power button next to the cd player for 10+secs and nothing. I've tried getting back into the diagnostic menu but its not coming up. I'm out of ideas to reset the system, any other ways i should try?
