I just purchased a 2007 prius and the mpe wma JBL audio system is not working. There is alsr the number 51825 RBS on the front. Can I replace it with one that has navigation as well? Also what is the button on the steering wheel marked map for?
If your car has navigation installed, it switches to the navigation maps. If you don't have navigation installed and you press it, an error/informational message will display on the screen.
