My dumb ass brother put in a new headunit into my truck and now everytime I turn off the truck it doesn't save anything my presets, my audio controls nothing. He said he had to run it as an acces. and now I hate turning off my truck. How can i fix this? Also when I listen to anything on the headunit it has a constant clicking in the background of whatever I'm listening to. I don't know what the hell that is either.
