Hey, thanks both of you for the information, the Proclips system seems like the way to go.
103west, about those "retaining clips along the edges of the upper storage compartment" are they such that the edges are pulled up until they release one by one. Is a tool used? I am asking because I would really like to install a 12 volt outlet in the upper storage compartment to service the GPS, I so dislike power cords dangling down, mickey mouse like.
