Navigation/Radio System 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. Theft-Deterrent Feature THEFTLOCK® is designed to discourage theft of your vehicle's radio. The feature works automatically by learning a portion of the Vehicle Identification Number (VIN). If the radio is moved to a different vehicle, it will not operate and LOCKED will appear on the display. When the radio and vehicle are turned off, the blinking red light indicates that THEFTLOCK® is armed. With THEFTLOCK® activated, the radio will not operate if stolen. 3-132
