A:AnswerThe stereo went in my brothers truck. He has onstar but never uses it. I wish I could tell you if it worked. It was a gift. But he doesn’t pay for onstar.
A:AnswerI think that is possible but I’m not absolutely sure. If they are factory probably not. After market I think can. Find the manual and see if it has external video output. I’m pretty sure it does.
A:AnswerI just had this installed for free. I believe as long as item cost over a certain amount, it’s free installation. I want to say anything over $99 is free.
