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.
