Guys and Girls,
Found this today on RAM website, it looks like a solid product, and the answer to all of us who have a car and a bike and don't want to buy two GPS units, I await the price with baited breath !

I have a standard mount from ram with a double ball arm that holds my TomTom, the only waterproofing is a plastic bag, this looks like a very neat solution.
I'll let you know when I get one, with some pics.
Snap.
