Your vehicle may have a navigation radio system that includes Radio Data System (RDS) with Program Type (PTY) selections that will seek out the kind of music you want to listen to and XM™ Satellite Radio Service capabilities (if equipped). The radio can also communicate with the navigation system to broadcast announcements on traffic, weather, and emergency alert communications. For information on how to use this system, see the "Navigation System" manual.

See your DeVille owner manual and the navigation manual for more information on your navigation/radio system.
