Navigation Audio System; Playing The Radio - GMC Yukon User Manual

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.
