Don't know why but i reinstalled my double din after 3 months of it sitting in the shop without it and i turn on the car but the head unit doesn't turn on. I check the head unit fuse and its good and also the radio fuse in the car and its also good. But when i used a tester on the cars radio fuse...it doesn't light up meaning its not getting any power to that fuse at all. Why is this?


Could the retained accessory power relay be the problem?
 


could be.

have you taken a DMM to the constant positive on the radio's harness.

Then try the switched and see if you get anything when turning the ignition to on or accessory.
 
check your power wire and ground for starters. also check if you have any exposed wires touching eachother
