Uniden R3 is the top performer these days. I did a ton of research prior to getting it a month ago. I was going to go with an Escort 360 until I dug into it. Lots of info on all of the top performers on

Also might want to consider a radar detector harness like this -

"This plug and play harness connects inline at the overhead console and allows you to connect your radar detector to either your windshield or to your rearview mirror."
I got the same thing for my Canyon and really liked it, so I just ordered one for the Camaro.
