Just buy one of the Touratech GPS holders for your specific GPS and it will mount perfectly to the 12mm bar on the GPS Mount Adapter.
As an example, I have the Garmin Nuvi 550 GPS. I have the Touratech GPS Mount Adapter (what came on your bike from the factory). I bought the Touratech GPS holder for my Nuvi 550 and it mounts to the 12mm bar of the Touratech GPS Mount Adapter. Here is a pic of it Mounted:
Thanks all! Now I have to nice a polite for a while
