Suction Cups for Radar Detectors: Choosing a Mount

A suction cup for a radar detector is a convenient way to attach a compatible portable unit to a windshield. Before buying a replacement, confirm that the mount fits the detector’s socket or bracket and the glass angle. A cup that fits physically may still be incompatible with the device. Clean the glass and suction surface as directed, attach it on a suitable smooth area, and check that the detector remains stable. Avoid locations that obstruct visibility or conflict with local rules; replace a worn cup instead of improvising an adhesive.
