4Runner Intermittent Unit No Power Issue

    My unit would not turn on at all today. I had to remove and re-insert the same 20A fuse for the radio in the 4Runner engine bay and then it came back on. Checking to see if there are any updates or instructions needed to prevent this? 

    Also, can my unit be updated to G12 OS?
