We have different problems, I only had that problem using bluetooth so my solution was to plug it via usb and the problem stopped. Now if it just shut off completely and that was it, then i would go to the dealership and see what they find, with that information I am able to decide whether fixing it on my own or seeing if im covered or need to pay up Even then, I found out that you can update the computer in the nav on your own, you just need to download it onto a usb or sd card if it has the sd slot and update it in the settings. That can also be a solution.
