Theft-Deterrent Feature (Non-Rds Radios); Radio Reception - Chevrolet 2007 Kodiak Owner's Manual

Theft-Deterrent Feature
(Non-RDS Radios)
®
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 will not operate and
LOC will appear on the display.
®
With THEFTLOCK activated, the radio will not
operate if stolen.

Radio Reception

You may experience frequency interference and
static during normal radio reception if items
such as cellphone chargers, vehicle convenience
accessories, and external electronic devices
are plugged into the accessory power outlet. If
there is interference or static, unplug the item from
the accessory power outlet.
AM
The range for most AM stations is greater than for
FM, especially at night. The longer range can
cause station frequencies to interfere with each
other. For better radio reception, most AM
radio stations will boost the power levels during
the day, and then reduce these levels during
the night. Static can also occur when things like
storms and power lines interfere with radio
reception. When this happens, try reducing the
treble on your radio.
FM Stereo
FM stereo will give the best sound, but FM signals
will reach only about 10 to 40 miles (16 to 65 km).
Tall buildings or hills can interfere with FM
signals, causing the sound to fade in and out.
