Reverse backup camera repeatedly ds not work and will display message saying camera unavailable. Sound system will go out with the center screen were no sound comes through (not even blinker sound). With a small child and have concerns driving when these issues occur, especially since they occur unexpectedly. Issues will occur a few days in a row, then work fine for a few days and then issues will occur again. Have been to the shop where they looked at the issue and was advised have to wait for a software update.
