Cheap shit Pioneer head unit seems to have died. I checked the fuse, in the driver's side footwell, indicated by a musical note and it hasn't blown.

Just wouldn't turn on one ignition.

Any ways I can diagnose without dismantling my interior? (Just don't have time for a while.)

they usally have a blade fuse behind the unit first, check that

I once saw a "dead head" sticker on a Cadillac.....lol

I'd say your power wire is loose...if there are no lights or elec antenna working?
