Navigation Audio System
Notice: Before adding any sound equipment to the
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/
retailer. 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 can interfere with the operation of
the vehicle’s engine, radio, or other systems, and
even damage them. The vehicle’s systems can
interfere with the operation of sound equipment that
has been added.
Notice: The chime signals related to safety belts,
parking brake, and other functions of the vehicle
operate through the navigation system. If that
equipment is replaced or additional equipment is
added to the vehicle, the chimes may not work.
Make sure that replacement or additional equipment
is compatible with the vehicle before installing it.
See “Accessories and Modifications” in the Index of
the vehicle’s owner manual.
