GMC 2004 Envoy Automobile User Manual


 
Radio Personalization
If your vehicle has this feature, it allows the driver to
return to the last used source: radio, cassette, or
CD using the remote keyless entry transmitter. This
feature can also store and recall AM and FM presets,
volume, tone, and the last selected radio station.
The number on the back of each transmitter, 1 or 2,
corresponds to driver 1 or 2. If transmitter 1 is used to
enter the vehicle, the last used audio source and/or
settings set by driver 1 will be recalled. If transmitter 2
is used to enter the vehicle, the last used audio
source and/or settings set by driver 2 will be recalled.
Theft-Deterrent Feature
THEFTLOCK
®
is designed to discourage theft of your
vehicle’s radio. The feature works automatically by

will not operate and LOCKED will appear on the display.
When the radio and vehicle are turned off, the blinking
red light indicates that THEFTLOCK
®
is armed.
With THEFTLOCK
®
activated, the radio will not operate
if stolen.
