Cadillac 2004 Seville - Manual (Page 211)

Your radio can store home and away presets. Home
and away presets allow you to use one set of preset
radio settings in the area where you live, and another set
when you go out of town. You will not need to
reprogram your presets every time you travel. With the
radio off and the time displayed, use fast forward
and reverse to select home or away presets. To select
the away presets, press and hold FF for five seconds
until you hear a beep. The next time the radio comes on,
the away presets will be active. To select the home
presets, press and hold RW for five seconds until you
hear a beep. The next time the radio comes on,
the home presets will be active.
When battery power is removed and later applied, you
will not have to reset your home radio presets
because the radio remembers them. However, you will
have to reset your away radio presets.
Theft-Deterrent Feature
THEFTLOCK ® is designed to discourage theft of your
radio. Your vehicle has a “built in” theft-deterrent feature
on each radio that is automatic – there is no
programming required. The radio in your vehicle cannot
be used in any other vehicle. When the radio was
originally installed in your vehicle at the factory, it stored
the Vehicle Identification Number (VIN). Each time
the ignition is turned on, the VIN is verified. If the
vehicle’s VIN does not match the VIN stored in the
radio, THEFTLOCK
® will be activated and the audio
system will not play. If the radio is removed from your
vehicle, the original VIN in the radio can be used to trace
the radio back to your vehicle.
