Whistler XTR 145 Radar Detector Review – Features


Whistler XTR 145












The XTR 145 offers total band protection from radar signals, 360-degree laser detection, Whistler’s patented VG-2 cloaking technology, and plenty more.

Total Band Protection

The XTR 145 will provide peace of mind as it is able to detect all bands used by the law enforcement including laser, radar (X, K, and Ka bands), VG-2, and safety radar bands.

When a laser signal is detected, the display indicates alert by illuminating the “V/L” and scrolling the signal strength indicators from right to left or display indicates an “L” on the
display. The audio alert will continue for a minimum of 3 seconds.

Do take note that for laser, if you are the targeted vehicle, the laser gun can often determine your speed within a few seconds after you receive an alert. Under this scenario, you don’t really have time to adjust your speed. However, if you are traveling near or behind the targeted vehicle and receive an alert, response time should be sufficient.

Note: Any laser alert, regardless of duration, requires immediate action!

Pulse Protection

Pulse (or instant-on) radar is more difficult to detect than conventional radar because it remains “off” until activated to measure the speed of a targeted vehicle.

When a pulse type transmission is detected, your Whistler detector sounds an urgent 3-second audio warning. The XTR145 will flash the alert strength indicators at their fastest rate. After the 3-second pulse alert, the standard alert pattern continues for as long as the signal is present. It is important to respond promptly to a pulse alert, since warning time may be minimal. Bottom line is whenever you hear any alert, slow down!

360 Degree Protection

The XTR-145 is equipped with 360 protection and able to detect signals from all radar, laser, VG-2 and safety radar systems wherever they come from; front, rear or from the side.

VG-2 Alerts

The VG-2, also known as a “radar detector detector,” is a special receiver used by police to detect signals radiated by a radar detector. Thanks to Whistler’s patented VG-2 cloaking technology, your detector will remain invisible to VG-2 detection.

When a VG-2 signal is detected, the VG-2 alert is sounded. After 3 seconds, the audio is cancelled and the VG-2 indicator flashes at a slower rate.

Every 30 seconds, the detector checks for a VG-2 signal. This cycle is repeated if the VG-2 signal is detected again. If no signal is detected, two beeps are provided indicating an “all clear” condition.

During the period a VG-2 signal is detected, a radar signal cannot be detected. However, because the VG-2 alert has confirmed that a patrol car is nearby, you are already aware of the potential for speed monitoring and can adjust your speed accordingly. Laser detection is not affected while a VG-2 signal is detected. Whistler XTR 145 specs

Icon Display

The XTR-145‘s bright icon display offers easy-to-read display to indicate power, city mode, radar band identification, and signal strength.

City/City I/City II Mode

Whistler’s Three Stage City Mode is designed to reduce the annoyance of automatic door openers, intrusion alarms and other devices which share frequencies with police radar. Generally, X band is used for these devices.

  • Press City button to cancel Highway mode and engage City Mode. The display will switch from “H” to “C”.
  • Press City button again to enter City I Mode.
  • Press City button again to enter City II Mode.

Note: After 3 seconds, “I” or “II” City Mode indicator turns off on the XTR-145.

  • Pressing City button a fourth time cancels City II Mode and returns the unit to Highway Mode.

In City Mode, weak speed/safety radar signals give an initial alarm of two beeps, and then remains quiet unless the signal becomes very strong. When the signal strength increases, two additional beeps are provided.

City I and City II Modes operate the same as Highway Mode, but in City I Mode, only the X band sensitivity is lowered. In City II Mode, X-band is not detected.

Caution: Some towns/small cities may still be using X band radar. City Modes do not change the audio alert for laser or VG-2.



Highway Mode

Highway mode provides full audio warnings any time radar (X, K, Ka, Safety Radar) or laser signals are detected, and is recommended for open road driving.

Alert Priority

When two or more signals are received at the same time, the alert priority is: Laser, VG-2, Speed Radar, Safety Radar.

Example: If X band is alerting, then suddenly a VG-2 signal is detected, the VG-2 warning will override the X band alert.

Quiet / Auto Quiet Mode

Pressing QUIET before a signal is detected engages Auto Quiet Mode, which automatically reduces the audio level after the initial warning to a low audio level setting.

Pressing QUIET during a radar/laser encounter silences audio alerts, while allowing visual alerts to keep you informed. After approximately 20 seconds, 2 beeps are provided on any new alert, and the unit then remains quiet.

Whistler XTR 145 Radar Detector Review – Vehicle Battery Saver Mode

The Vehicle Battery Saver Mode automatically shuts off your detector within 3 hours if you forget to turn it off. The timer is reset if the detector is turned off, unplugged or any button is pressed before the 6 hours have expired. The detector will alert you with an audible and visual warning before it shuts off.


Mount the unit as low as possible near the center of the windshield. Take note and do not mount the unit behind wipers, ornaments, mirrored sunscreens, etc. These obstructions have metal surfaces which can affect radar and laser signals and reduce critical warning time (Regular tinted glass does not affect reception.).

Also some windshields have an Instaclear™ or Electriclear™ type coating, which affects radar signals. Consult your dealer or the owner’s manual to determine if your windshield has this coating.

Avoid placing unit in direct contact with the wind shield and to reduce the possibility of theft, conceal the unit when not in use.

Power On Self Test & Volume

Each time your XTR-145 detector is turned on, an automatic self-test sequence confirms that the speaker and visual displays are functional. To increase the volume, continue turning the volume knob.

Reset Features

If you’ve messed up with the features, don’t worry as all user features can be reset to factory settings.

Care & Maintenance

During the summer months, avoid prolonged exposure to direct sunlight byremoving your unit from the dash when your vehicle is parked for an extended period of time. Do not spray water, cleaners, or polishes directly onto the unit. The spray may penetrate through the openings and damage the unit. Also, do not use any abrasive cleaners on the unit’s exterior.Whistler 145 review

Is it Legal? 

Radar detectors are completely legal to use in non-commercial vehicles in 49 states. Virginia and Washington D.C. are the only places in the United States that currently ban radar detectors. Radar detector use in commercial vehicles has been prohibited in the U.S. since 1995 and radar detectors are also illegal in most Canadian provinces.

Whistler XTR 145 Radar Detector Review – Customer Review

At the time of this writing, the rating for the Whistler XTR-145 is 4.1 out of 5 stars. The majority of the ratings in on 4 and 5 stars indicating a good customer satisfaction.


  • Easy usage right out of the box
  • Total band protection
  • Good display
  • 360 degree protection
  • Alert priority
  • Invisible to radar detector
  • One year warranty



The Whistler XTR-145 is an entry level radar detector with many supposed great features. However, when it comes to performance, it disappoints as the alert alarms will go off without any reasons and sometimes it can’t detect the radars or lasers it is suppose to. Quality is also an issue as the chord tends to break after being used for some time.

If you have a higher budget, I will advise you to go for the Whistler CR90 or the Whistler CR85 which are better options.
