with the CD. If the CD plays properly in another CD player, the radio/navigation radio
will need to be exchanged.
Unable To Play Certain CD's
The following should be closely observed when a customer complaint of not being able to
play certain CD's is encountered:
Is the CD scratched? Check for visual scratches on the CD. Test the CD in another
vehicle or household CD player, to duplicate concern.
Is the CD a store bought CD, or custom made? Custom made CD's can vary in quality
depending on the speed the information was written to the CD. Store bought CD's
are carefully replicated, which is a higher quality than simply "etching" the
information on a CD.
Are CD labels attached properly? Check for peeling, folds, or an uneven surface
mating.
What Is The Format Stored? (MP3 Capability)
To verify, place CD in a computer CD-Rom.
Read the contents of the CD.
Verify only MP3's are recorded on to CD.
What Is The Format Stored? (WMA Capability)
The following radios support WMA format:
RNS 510
