Hi Nav 44. Did you solve the reboot problem? Mine is a 4Runner 2014, and just started rebooting so much, that I am not able to install the software update because of the rebooting issue. Please, let me know if your rebooting problem was fixed and how did you made it?Not the answer I was hoping for, but it is still appreciated. It is somewhat mind boggling that Toyota would build (or contract with someone who would build) what is essentially a computer without a recovery mode. At least I now know what to look for in aftermarket units.
