How to troubleshoot CD issues with the car stereo.
IMPORTANT: There are many car stereos that are not designed to play CDR or CDRW discs. Check the operating instructions that came supplied with your stereo for disc compatibility. Manuals are posted on your model support page.
NOTE: Because each of these steps represents a possible solution to this issue, test for proper functionality after completing each step.
- Play different discs to see if the issue occurs with all CDs or just a few.
NOTE: If the issue only occurs with a few CDs, then the issue may be with those discs.
- Examine the CD for any fingerprints or smudges, and clean if necessary.
- Check all wires to verify a good connection.
- Perform a reset on the unit.
NOTE: The laser pick up may be dirty and need to be cleaned. Sony does not recommend the use of an over-the-counter CD/DVD player lens cleaner. These lenses should be cleaned by a factory-trained Sony® technician only.
If the issue is still unresolved, service may be required.  Go to Product Repair.
