    I have a 2012 Tundra and I had installed an Axxera Nav headunit about 8 months ago. About a week ago I heard some popping and thought one of my connections was not crimped well like it would if you had a speaker terminal miscrimped.

    Anyway, I opened up the dash, pulled the unit out and when I had the key and radio on I was checking all the connections. Next thing I know the head quit working.

    I checked all the connections and none were loose. I checked the 15a fuse in the head and it was fine but I replaced it anyway.

    I checked the fuse box under the driver dash/floor area, pulled the 7.5a for ACC and it was fine.

    I don't know what else I could check or replace to get it working. I pulled the unit from the dash today, ran a voltmeter and it's not getting power at all. I'm certain it's a blown fuse somewhere but I don't know what else to check.

    I don't have a system in my truck so I know it's not anything related to that.

    Anyone ever have this problem? If yes, what should I do to fix it?

    Based on the diagram for 2012 Tundras, it looks like there might be another 15A fuse labeled Rad. No. 1. Perhaps in the engine bay fuse box? I don't have a 2012 so I'm not sure where it would be exactly. Drawing key indicates Left (drivers) side of the engine bay.
