I’m thinking about to upgrade my factory stereo to an android head unit. 1. Took the factory stereo out today and tried to find out these connectors 1 to 15. Anyone know what these are? 2. This factory stereo has a small separate unit (connector 12 to 15) attached to the main stereo. What is this small box for? 3. Without connected my factory stereo back and fired up my car. The only buttons working on the steering wheel are the dynamic cruse control and lane departure buttons. Is the android head unit will pick up the remaining buttons? 4. Does anyone has any recommendation on which android head set to get and will work on all buttons on the steering?
