When I turn on the car the radio display shows a bunch of scrambled letters/symbols and then goes blank. The ***** and buttons won't work on the radio panel but the steering wheel buttons work to operate the radio. I tried restarting the car a few times. It started to work again after being off for about 30 minutes. A few days later it did it again. But the buttons on the steering wheel still work. Is there an easy fix to this?
