NEW Exclusive TotalShield™ Technology
Our new TotalShield™ technology makes the STi-R completely invisible against any type of radar detector detector. Not only will it keep you unseen by the current VG2 and Spectre, it will be completely undetectable by any future threats as well.

Digital Signal Processing (DSP)
Our patented AutoScan™ feature continuously analyzes all incoming signals and automatically rejects unwanted false alarms. This gives you, the professional driver, the perfect balance of long-range detector performance without those annoying false alarms.

Clear Digital Voice Alerts
The STi'-R's easy to understand digital voice alerts keep you informed without taking your eyes off the road. For extremely noisy environments, simply install the amplified speaker (included).

 

High Definition Text Display
Using the brightest alphanumeric display possible, the STi-R is easy to read from any angle. Choose from three different meter modes.

City Mode Filtering
Choose from two levels of City mode filters, including City Standard and City NoX for quiet operation in and around town.

Mute and AutoMute
The STi-R comes with BELTRONICS' AutoMute feature, which automatically reduces the volume level during an alert. Or, simply press the large front-mounted Mute button on the control module during an alert to instantly quiet the audio.

Brightness Control with Dark Mode
The STi-R has four levels of brightness, including an auto mode which automatically changes the brightness based on the ambient light in the vehicle. You can also select for dark mode for complete stealth operation.
