First the pre-set button lights failed. Now the face lighting where the time and station is displayed is starting to fail. When that goes the radio will be totally dark and since most of my driving tends to be in the dark, that's going to be a problem. This the factory radio/CD player and everything else is OK and works. Is there a way to replace the lights or does the entire radio need to be replaced? If so, is that a job that can be done by a guy with some skills but not an overabundance? Thanks for any insight that can be provided!
