I have my passport 8500 installed to the right of the rear view mirror and the wiring goes straight up to where the roof meets the windshield. It is really stealthy becasue when a cop pulls u over and is talking to u he can't see that high up from his angle. Just stand next to ur driver's side door and look at what u can see. Put the radar out of that field of view. Another good thing about that location is that it doesn't distract my driving. At first I had it over my dash in the middle of the windshield and i couldn't stand it there.
