Audio System(S) - GMC Sierra 2005 Owner's Manual

The DIC will begin scrolling through the languages in their
particular language. English will be in English, Francais

you see the language that you would like, release both
buttons. The DIC will then display the information in the
language you chose.
You can also scroll through the different languages
by pressing and holding the trip reset stem for
four seconds, as long as you are in the odometer mode.

Audio System(s)

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.
Notice: The chime signals related to seat belts,
parking brake, and other functions of your vehicle
operate through the GM radio/entertainment system.
If that equipment is replaced or additional equipment
is added to your vehicle, the chimes may not work.
Make sure that replacement or additional equipment
is compatible with your vehicle before installing it.
Figure out which audio system is in your vehicle, find out
what your audio system can do, and how to operate
all of its controls.
Your vehicle may have 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 2-23 for
more information.
