2013 BRZ Limited Fujitsu head unit suddenly stopped working.
 

Hi everyone, this will be my first post because it happened a couple days ago and is baffling me beyond belief - took the B to the shop to get new tires put on. Get it back and head unit is completely dead. Didn't have time to have them sort it due to work sched and shop's hours almost always being the same, so until I can have them take a look I'm trying to figure this out myself.


I think I found the right fuses and checked all of them - nothing blown. Everything else in the car aside from the head unit works as it did, including both d/c ports and all the lights and so on.


Any ideas?

Aaand lo and behold thing up and came back to life after I wrastled with it...... guess like any electronic piece - take it out and threaten to throw it away and it starts working again....
