It's funny how the Escort 8500 is so popular and almost nobody is saying a word.
I own three. One is hardwired into my son's WRX, my wife used mine for a trip to Chicago and never gave it back
, so now I have one that I hardwired into my 930 and use the window mount for my S4.
A year or so back, Autoweek did their own test trying all the available units in their long term road test cars. The Passport was number one and the 8500 was 2nd or 3rd. The 9500 wasn't available then. I'm sure the V1 is on par, but not hands down better, just more $s.
Cheers
