Beltronics STI Driver

The new TotalShield technology makes the STi 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.

Next Generation of Laser Protection

Multiple laser sensors, strategically positioned in the case, continually search for laser gun signals. Maximum range, including superior off-axis protection, is standard.

Easy-to-Use Options and Controls

The STi is simple to use and operate. Preset at the factory, the STi is optimized for short or long hauls in North America. However, you can customize up to 9 features to meet your specific driving style.

Clear Digital Voice Alerts

The STi’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 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 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 detector or SmartPlug™ (included) during an alert to instantly quiet the audio.

Brightness Control with Full Dark Mode

The STi 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 and use the power-on and alert indicators on the SmartPlug™ for complete stealth operation.

Comes Fully Equipped

The STi comes complete with a comprehensive owner’s manual with quick reference card, quick-release windshield mount with suction cups, coiled SmartPlug™ lighter adapter, amplified 12-volt speaker, direct wire SmartPlug™ and a durable hard-shell metal travel case.
