Lately I've had the dealer replace my homelink mirror, and overhead control unit module. I now have homelink and interior lights but other problems that we thought would be cured by the OCP replacment still don't work.
Voice control, buttons on the right side of steering wheel, audio....nav....tel..... in the multi-function display are disabled. radio has to be turned off manually when car is off and door opened.

Anyone have any ideas ?

Oh, and while driving I'll get a message on the comand screen - ' Please start the engine, radio will turn off in 3 minutes ' which it does.

It can switch it back on but in about 30 min. it does the same thing.
Navigation is also frozen at my home location (shows 8 satellites, so I guess the antenna is working).

Any suggestions ?
