The Radar Blindspot System is based on microwave radar technology for extended distance and sensitivity. Our BSS3 kit adds an extra set of eyes and warns the driver if there are any vehicles approaching in either blindspot before and during a lane change maneuver. Our system uses GPS to initiate operation above 20 MPH eliminating potential fault alerts. Unlike other systems, it requires no drilling into the bumpers. Radar Sensors install behind the bumpers hidden with included metal bracket hardware and alert the driver with two compact LED Indicators mounted on the “A” Pillars and a small hideaway adjustable speaker. This Microwave system is more accurate than previous ultrasonic based sensor solutions from other companies.

Kit also includes newly revised “Reverse Cross Traffic Alerts” for backing/reversing out of a tight space when visibility is limited while vehicles are approaching from left or right side.
