Navigation Audio System Notice: Before adding any sound equipment to your vehicle, such as an audio system, CD player, CB radio, mobile telephone, or two-way radio, make sure that it can be added by checking with your dealer. Also, check federal rules covering mobile radio and telephone units. If sound equipment can be added, it is very important to do it properly. Added sound equipment may interfere with the operation of your vehicle's engine, radio, or other systems, and even damage them. Your vehicle's systems may interfere with the operation of sound equipment that has been added. Your vehicle has a feature called Retained Accessory Power (RAP). With RAP, the audio system can be played even after the ignition is turned off. See Retained Accessory Power (RAP) on page 2-22 for more information. The audio system is operated using navigation system menus. The audio menus are explained in this section. Main Audio Menu e/ z (Audio/Adjust): Press this key to view the main audio screen. 4-51
