I just got an Audi S4 so I'm looking for a good radar. I've had the V1 for years but swithced to the Escort 9500i a year ago because of its GPS lockout. I joined this forum since I want to do custom install with the new ride. Looking at *** ML360, V1 (maybe) w mirror display, Escort 8500ci Plus, Bel Sti-R. Leaning towards the 8500ci for the money and perf. I'll probably post a question about this later after doing some reading.
