GMC DENALI UNDER THE RADAR

This Denali was equipped with an undetectable front and rear radar detector plus a front laser jammer.

Starting with the cockpit there is little evidence that a laser/radar deterrent was added. In the above photo, the alert lights are off and virtually undetectable.

We flush-mounted two red LED’s to the interior lower sides of the instrument cluster’s sun shroud. The LED’s provide a visual alert of the presence and location of a radar and/or laser source.

The separate left and right LED’s work in unison with separate quarter-sized piezo buzzers that are recessed and mounted within the left and center air conditioning ducts. The left audio/visual alert set indicates the presence of a forward threat while the right audio/visual alert set warns you of a rear threat.

In this photo, you can see the illuminated LED’s in the lower left and right corners of the instrument cluster shroud.

In an empty panel next to the AC control, we installed a dual concentric control and a status LED.

A single control unit features an on/off knob plus inner and outer controls. One control allows you to select sensitivity for either city or highway driving while the other control allows you to vary the volume of the two piezo buzzers.

Depending on the vehicle owner’s preference, we can position the controls in a totally concealed location while the dash or console may offer the most access convenience.

The dual color LED status indicator displays yellow when in the city mode and green for the highway mode.

With the front grill removed, the radar receiver and laser detector/jammer are exposed. The radar receiver is mounted just under the latch mechanism via two drop down brackets and a 1/4-inch thick polymer plate. This radar collector bell and sensor can be mounted behind any non-metallic material such as plastic, fiberglass or carbon fiber that will allow the uninhibited passage of high-band radio frequencies.

The laser device is mounted to the top of the front bumper and fits neatly between the bumper and grill. The laser detector/jammer functions in a band that must have a clear and totally unobstructed view of the road ahead in order to detect and defuse the laser light beam.
