Just that is was big, and it was unable to get a lock anywhere other than on my dash.

I tried to mount it under the dash, but no luck.
I am going for a very clean install and a big white hockey puck on the dash just did not cut it. (At least the NavMan is Grey and Black ) Plus my Co-pilot GPS was Serial and the Navman is USB.

It should (They claim) be here early next week so I will keep you updated.
