Hi, can anyone please tell me how to fix my avic f900bt? After awhile the screen freezes on the welcome image and stays that way. If i insert a CD it works, but the menu button and the maps button are not working. I updated my device with the latest version 4.0 but it's still the same. The boot button does nothing. Help please.
