Radar detectors have always been a necessity for those drivers with a "heavy" right foot. Although not a license to speed, radar detectors do let the driver know if any radar is being emitted within a certain radius. There are two types of radar systems: - Remote Radar: Remote radar detectors are hardwired to the car and mounted in an inconspicuous manner. A control unite inside the car adjusts the volume and alerts the driver of the type of radar that was detected. "Sensors" are also mounted in the front grille and rear bumper of the vehicle to give you 360º of protection. - Dash Mount: This type of radar detector can be mounted in the vehicle either with Velcro on top of the dashboard or with a suction cup to the windshield. Dash-mounted radar detectors can also be wired directly to the ignition switch to shut on/off with the vehicle.
