Hello guys,
was wondering if anyone had any suggestions on fixing my semi-dead head unit. Randomly the other day I was swapping to reverse which is suppose to trigger the back up camera on the head unit but it just turned black and never turned on again. The radio still works as my bluetooth is autoplaying my phone's music when it is on.
The subaru local mechanic i went to doesnt touch radios and a guy that does stereos suggested unplugging and replugging the battery (did not work). Has anyone had this issue? Is this a bad wire? Do I need to pull the head unit out to check? Would it be easy to fix myself? Also I don't think its the fuse since i swapped the radio fuse with the spare unless theres more fuses connected to the head unit...
Should i just bring it to the dealer?

Thanks guys!
