Elevens,
I am currently in the process of installing my Escort 9500ci radar-laser system. It came with a GPS pod as well, because it is location aware of traffic camera lights, etc...pretty nice feature. Anyway, i mounted the pod INSIDE the stock antenna fin. Pretty easy to get to. The rear dome/map light pops out pretty easy, and inside you will see the nut that the holds the fin on. Once you take the fin off after clipping the stock wires, you need to drill out the hole the wires are routed up into the antenna. But first, take apart the antenna and gut it out. otherwise, there is no room. Pretty crazy design in there...So anyway, i now have the GPS pod for my Escort system mounted in the stock antenna fin. Routing the wire is another story however. I am running mine down the b-pillar and forward along the driver door.
