I've owned this unit for about three years, using it lightly (I don't drive much, and usually listen to the radio). When it worked it sounded decent. After a year or so, it sometimes had problems: wouldn't read any CD (purchased, or burned), and the volume knob wouldn't work and it would go to zero volume. These occurred randomly several times. The CD would work again in a few minutes to a few days. Pulling off the detachable face and putting it back sometimes got it working again (or was it coincidence?) The CDs I played have always been clean and in good condition. The volume knob alsways worked correctly after a few seconds. During the past few weeks the CD player has not worked at all. I gave up and got rid of the Aiwa. I did meet someone who has the same unit and they said theirs has worked perfectly, and he uses it often.
