Product Features

Number of Modes
This number indicates how many modes the radar detector can be set at. Most detectors will include a city and highway mode. More advanced radar/laser detectors will offer more modes to suit your needs.
Dark Mode
Dark mode is a brightness option. Unless there is an alert, the unit will be completely dark.
Voice Alerts
The feature designates if the unit uses voice alerts. Voice alerts will audibly alert the driver of various warnings.
Auto Mute
The auto mute function will conveniently mute the alert tone when the alert lasts for an extended period of time. This is for the drivers convenience during extended encounters.
Auto Shut Off
A convenient feature that turns off the unit when the ignition is turned off.

Product Specifications

Radar Display
The type of display that the radar detector has.

LED Displays: Tells the driver what he or she needs to know through a bright LED display.

LED Icon Indicators: Tells the driver what he or she needs to know by illuminating icons and symbols.

Text Display: Tells the driver what he or she needs to know by illuminating text on the display.

LED Display
Signal Strength Meter
This feature means that the unit displays that strength of the received signal.
Brightness Control
If the brightness of the unit can be conveniently adjusted and controlled, it will be listed here.
Turn-on/off Select Bands
Many radar detectors can detect many different bands of signal. This feature designates if the user can select what bands he or she has on or off.
Unit Mounting
Different radar detector are attached to the vehicle in different ways. The most common is for it to be suction-cupped to the windshield. This allows the unit to be moved from one vehicle to another with ease. Another mounting option is called remote-mounting. A remote mount unit is directly installed into your vehicle.

Other ways to mount your radar detector include Velcro and adhesive.

Suction cups
Power Source
The power source is the method in which the unit receives power. Some units will be powered by batteries, while others will need to be plugged in to an AC or DC power source.
12V DC Car Adapter
Direct Power Accessory
If there is an optional accessory to the unit that will provide power, it will be listed here.
Travel Case Included
If a protective travel case is included, it will be listed here.


Number of Detected Bands
This number indicates the number of bands the radar/laser detector protects against. The term band includes different radars, lasers, and safety signals, among others. The higher the number, the greater the protection.
X Band
X Band is a frequency used for detecting speed from a police radar.
K Band
K Band is the most popular radar frequency band that is used today. It is able to detect speeds from a stand still location, or from a moving vehicle
Ka Band
Ka Band operates within the frequencies 26.5-40 GHz. This is the newest introduced radar band and it is becoming more and more popular. It rarely has a false alert.
Ku Band
Ku band ranges from 12-18 GHz when used in radar applications.
This feature specifies if the unit will detect lasers.
VG-2 Immunity
The VG-2 detects radar detectors. Radar detectors with VG-2 immunity will be immune to the VG-2 radar and alert the driver when they are under such surveillance.
Pop Alert
Some radar guns operate in a POP mode so they can get a speed reading of a target vehicle extremely fast, resulting in most radar detectors not being able to consistently signal an alert. There are very few radar guns in service in the U.S. capable of POP mode operation. If your radar detector is Pop Alert capable, you may notice an increase in Ka-band false alerts when POP mode radar detection is switched on.
