For convenience, the Cobra XRS 9990 includes a digital signal strength meter that provides visual and audio alerts, indicating the proximity of detected signals. The ultra-bright data display ensures readability in varying lighting conditions, enhancing usability and safety. The unit's compact design integrates a built-in 8-point electronic compass, aiding navigation.

Additional features include the Safety Alert and Strobe Alert, which notify drivers of emergency vehicles and road hazards, and the VG-2 Alert that warns the user of radar detector detectors. The device is powered via a 12V DC power cord, suitable for standard car power outlets, and it comes with a suction cup mount for easy installation on windshields. The Cobra XRS 9990 combines sophisticated detection technology with user-friendly features, making it a reliable companion for drivers seeking enhanced situational awareness on the road.
