What does 'INVALID' mean on my Dual Car Receiver?
If the Dual Car Receiver displays 'INVALID', it means the WMA file is copy-protected by DRM (Digital Rights Management). Write the disc using valid audio files with .mp3 or .wma file extensions.
Why won't my Dual XDMA690 Car Receiver accept a disc?
If your Dual Car Receiver will not accept a disc, it could be due to a couple of reasons. First, the CD mechanism position might be out of alignment; press the EJECT button for 3 seconds to reset it. Also, check for and remove the two transit screws located on top of the unit.
