The Aftermarket Visor Clip suits Uniden Models DFR7 / R3 / R4 / R7 / R8 Models and enables you to mount the detector on your sun visor. We would recommend that you also purchase a Direct Wire to go with it for a nicely integrated look. Note: Check how level your Visor sits as it may not suit some cars where the Visors are facing downwards in their normal position.
