radio stations using the presets and steering
wheel controls if the vehicle has them.

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/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.

operation of your vehicle’s engine, radio, or
other systems, and even damage them. Your
