I think I went through 3 CD players in the first 7 years in my Civic. After that I just used the radio. A CD player is a very sensitive machine, and it's amazing they can make them work in a car at all. You're talking about aiming a laser at a spot that's, what? a few millionths of an inch wide? as the car is bouncing and bumping along the road.
Still, I'm sorry to hear that yours has gone on the fritz. I'd probably take it in to a good car-audio shop and see if they can fix it cheap, and otherwise have it replaced.
