This adapter from Ultimateaddons is designed to allow you to mount your TomTom Rider powered mount to an Ultimateaddons 3 prong mounting attachment. This adapter converts the 4 hole AMPS layout to have a 3 prong female connection which then allows you to mount directly to a 3 prong attachment / adapter.
Pictured below is the adapter connected to the TomTom powered adapter (supplied by Tomtom) and the power adapter then connected to the Ultimateaddons mirror mounting kit.
