Just finished this up last night. Been trying to come up with a semi-permanent way of mounting my GPS so that I don't have to worry about the windshield mount or adapter advertising the fact that I have a GPS, and I could just leave the GPS in the car. This is what I came up with:
It could be a bit prettier, but I'm happy with it. The GPS can be removed from the visor if I want to use it in another car or update the maps.
I've done the V1 in the clock pod thing too, but I used a tinted piece of plastic (similar to the clock plastic but no clock buttons). And I got some extended screws and mounted my V1 right underneath the dome light, using the dome light mounting points. Much harder to spot from outside (I used to have it above the rear view mirror), and much harder to steal (since it's screwed into the roof.)
