My motherboard died and I couldn't reload the firmware. It was stuck on 100% read progress. I bought another one on Ebay and it works great but I am having some issues.

 

First, I cannot do anything with the GPS while I'm driving. I never had this problem with the old board.

Second, I have a whack of warning screens. One is brake switch is not properly connected or something like that.

I haven't tried to watch a dvd yet but I'm sure it will error out.

 

I haven't changed any wiring since installation. When I installed it, I moved the proper wire in the harness and grounded the brake switch.

 

Is there something different with the motherboard I have now?
