My cd player works that is without issue, however.... everytime I try a dvd, it says it is reading and then gives me an error message. I tried to watch a youtube video on how to do it through my navigation system but that only confused me more. I am unsure if it needs cleaned or what. I was informed by someone working at the store that they no longer sell head cleaners for in dash cd players and that would likely mess up my laser and I would be better off using canned air. I am just weary of moisture.
