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.

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.
AC Adapter (Included)
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.

March 30, 2014 - My Review of the Whistler CR90 radar

March 30, 2014

Whistler CR90 radar
The Whistler CR90 Portable Radar Detector is in my budget for realistic affordability. I received my detector March 21, 2014, and it works as well as any radar in its price range. I am not a speed-demon but on-the-side-of-caution, I am grateful when I do need it. There are many price-ranges that do determine a radar’s performance. Simply stated, “The more advance technology a company puts into its product will cost more”. With that said, I choose to use my budget as a ruler to determine the best radar for me.

I have read forums by customers and professional critics about radar detection quality. Given all the environmental conditions and variables driving conditions, the consensus is “If the radar detects too late - - than it did not do its job (talking about detectors under $200)”. For those with a need-for-speed then the best up-to-date technologically advanced radar is worth the price. For me, The Whistler CR90 meets my needs for city and interstate driving (even with false alarms, etc., it is in my price-range). This radar is up-dateable via USB with a PC; but not for Mac users like myself.

For what-reasons, the majority of radar detectors are non-compatible with Mac for updates. My get-around is to use someones PC to periodically update my detector. Last but-not-least suction cups to hold my detector onto the windshield; my preference is no suction-cups. Look-around for bargains, clearance. Companies will throw-a-bone and include a mount to securely attach to your rear-view mirror.

Two things: 1) make sure the mount WILL PROPERLY FIT the rear-view mirrors cylindrical shape stem (research, call the company, etc.); 2) if mount not included, buy it separately.

In conclusion, I consider this Whistler CR90 a value-buy worth looking into (also I got the Rogue Radar Mount R2011-103-WHIST-CYL-RM). Both the radar and the mount are well made products, and because they both serve the designed purpose, I give a five star for its practical application and cost.

If it does what it is supposed to do--price.

Is this the newest and also the best detector Whistler makes? Do they have more advanced electronics to compete with Escort/Beltronics?
charlieboy on Jan 19, 2015
Best Answer: Hello David,

An argument can be made that their "best" detector is the Whistler PRO-3600, along with the various add-ons it has available to it.
