2016.5 CX-5. Started the car one day and the infotainment unit kept rebooting. The backup camera worked and the last radio station used prior to the fault would play. But no access to anything as it would continue rebooting. Took it to the dealer and they first tried to update the software, but couldn't do that due to the constant rebooting. They installed a known good CMU unit and that fixed the problem. So I had a new CMU unit installed. Works fine so that fixed the problem.
Posting this in case someone else has the same issue. Tried removing the nav chip and the 3 button reset, but no dice.
