Q: Navigation screen, backup cam, and bluetooth not working
The dealership just replaced my battery last week. This week, the navigation screen, backup cam, and the bluetooth quit. All other electronic components are fine (all buttons, radio controls, A/C - all work well). I returned to the dealer and they claimed to have taken the unit apart and they can’t diagnose the problem. They said that I’ll have to have it replaced for $2K! Could this have happened from a faulty battery installation and what is your advice?
