I know that this is not exactly the question that Frank asked, but here is my solution for mounting the GPS V. I puzzled about the same idea of bending up a mount, but didn't want to drill holes in the radio face plate. So I settled for the ProClip mount
http://www.proclipusa.com. This puts the V in a perfect spot for you to glance at it without looking down under the radio. I used a Garmin base mount glued to the ProClip to hold the V in position.
The downside is the exposed wires, but I cable-tied them together and they run right down a seam in the dash panels and are not a big deal. The antenna is under the dash cable-tied to a cross bar where it works perfectly; I get an average of 8 satellites most of the time. (Make sure you don't mess with or block the pax side airbag when doing anything under the dash.) I powered from a tap on an unused "key on" spade on the driver's side fuse panel. The ProClip has sticky on it, but it is under some tape; I left the tape in place so I can quickly remove the whole thing. The wires roll up and stuff behind the gearshift trim and the V goes into the glove box.
Here is a pix of the whole thing. The little screen in front of the radio keypad is my Parrot; I don't even own a tape cassette so blocking the port is not a big deal. All the radio buttons are still easily reachable.
