DVD Random Track Selection
WARNING: This page is about a different car, the 2007 Pontiac G6. However, it is still accessible from the selected car via links, so may be relevant.
The radio allows random track functions for audio CDs only. When the RDM button is pressed and released, the DVD player enters the random one disc access mode. The tracks on the current CD plays in a quasi-random order. Quasi-random means the tracks are picked randomly. No track is repeated until all tracks are played.
The DVD player mutes while switching tracks in the random access mode.
If the DVD player becomes the active audio source, the radio defaults the random access mode to OFF.
