Navigation/Radio System

Your vehicle may have a navigation radio system.
The navigation system has built-in features intended
to minimize driver distraction. Technology alone,
no matter how advanced, can never replace your
own judgment. See the Navigation System manual for
some tips to help you reduce distractions while driving.

Theft-Deterrent Feature

®
THEFTLOCK is designed to discourage theft of
your vehicle's radio. The feature works automatically
by learning a portion of the Vehicle Identification
Number (VIN). If the radio is moved to a different
vehicle, it does not operate and LOC, LOCK, or
LOCKED could display.
®
With THEFTLOCK activated, the radio does not
operate if stolen.
