I currently run a Passport 8500 X50 and like it... but there are better units out now.. the 9500ix is probably what I would get if in the market for another. Shop around online-- you can find a deal. Company site:

The Escort Live setup is really cool. You load an app on your smartphone.. and then have a cable from phone to radar detector.... you get alerts on your phone..speed camera updates.... alerts when you're going too fast, etc....plus a whole lot more.
Right now I get sound from my 8500 X50 via cable into my Mix-It box (
http://www.mixitproducts.com/) and plug it into the priority channel.. so it will cut my music and GPS which are plugged into other channels.
From the Mix-it I usually run a blue-tooth transmitter so I can then pick up everything that goes into the mix-it from my Sena SMH10. Sometimes I also just plug earbuds right into the Mix-it... or even output directly to the RT's audio system.
Do not EVER buy a Rocky Mountain Radar unit.
These guys did great reviews a few years ago.. wish they were still testing current models.
