A music note symbol next to the CD symbol indicates it is a music CD. A small square symbol next to the CD symbol indicates a DVD containing data is loaded in the player. A film symbol next to the CD symbol indicates a DVD movie is loaded in the player. See "Playing a CD" under Navigation Audio System for more information.

F. CD Changer Information: This displays CD changer information. The six horizontal lines represent the six slots of the CD changer starting at the bottom with disc one.

G. Time/Radio/CD/CD Changer Information: This displays the time. Radio frequency, audio source, CD, or CD changer information will also display here briefly if any of the following occurs:

    • The radio is on and the screen is not a radio, CD, or CD changer main screen.

The road you are currently traveling on, the estimated time to destination, and the distance remaining to destination will display.

M. Reconfigurable Keys: These keys are reconfigurable because their function can change with the different screens and menus of the system. These six reconfigurable keys control the prompts on the left side of the navigation screen. If you see a triangle or carat symbol in the upper right corner of a prompt, it means that key is programmable. Once the function you want is active, press and hold the key until a beep sounds. The new function is now programmed and will display as the prompt for that reconfigurable key. See "Setting Preset Stations" under Navigation Audio System for more information.
