Audio system with navigation

Stay entertained and always on track with this audio system with navigation, which includes:

  • OnStar® navigation,1 offering turn-by-turn guidance almost anywhere; most new GMC vehicles come with the OnStar Directions & Connections® Plan standard for the first 6 months
  • AM/FM stereo with convenient seek-and-scan, auto-tone control, speed-compensated volume, Radio Data System® (RDS)2 (for receiving broadcast information, traffic alerts and weather bulletins) and TheftLock®3
  • MP3-compatible CD/DVD player, for listening to digital music files you've burned on a disc
  • USB port4 for added functionality
This feature is not available with OnStar delete.

Visit for coverage maps, details and system limitations. Services vary by model and conditions. OnStar acts as a link to existing emergency service providers.
2 Radio Data System functions only where stations broadcast RDS information.
