Are you sure its the cd player and not the cds?
If your 100% sure that its the cd player.... you can
see whats wrong and get it fixed ... if you still have warrenty on your car, call the place where you got your car and ask them to check it up... and they'll probably fix it for free (with the warrenty)
OR
buy a cd players cost from 70 dollars (the cheap ones) and up... soooo think about it
