This mounting frame for car radios is specifically designed for the installation of double DIN car radios in the dashboards of commercial vehicles. It positions the radio chassis in a pre-shaped opening and secures it to the vehicle's original mounting points. This ensures that the device is held securely and prevents movement due to vibrations. Installation is done by inserting the frame into the dashboard opening, aligning it with the vehicle-specific mounting points, and screwing it in through the existing holes. The radio is then slid into the frame and held in place by the trim. Typical applications include retrofitting double DIN car radios into the dashboards of Mercedes Sprinter W906 and first-generation VW Crafter, where precise mounting and even alignment of the trim are required.
