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.
Audio Steering Wheel Controls
Some audio controls can be adjusted at the steering
wheel. They include the following:
VOL: Press the up arrow button to increase volume and
the down arrow button to decrease volume.
