This cradle is designed to securely hold the two larger OS GPS devices, the OS Aventura and OS Trail. It uses a spring clip to hold the GPS device in place.
The mount is designed to be compatible with 'RAM Mount' type fixings. You will need a Ram Mount base kit suitable for the application you are planning on using it for - there are base kits for specific vehicle models, as well as versatile mounts with suction fittings, motorbike handlebar brackets and more. Ordnance Survey do not stock the base kits, but they are available from Ram Mount re-sellers.
