I got into my car last night to go to work, and when I turned the car on I got a "CD Error" message on the head unit's display. I turned the input nob and the setting went to FM (which worked), but from there on would only cycle between AM and FM, no CD player or USASpec functionality. Even after starting/stopping the car several times over several hours, it is still hung up on AM/FM. Everything seems to work fine, including ejecting and accepting CD's from the slot in the dash. I tried all the buttons but to no avail. Has anyone had this issue before? Anyone have ideas of what to try to get my stereo back in working condition?
