I have ALP installed and like it. After research, it seemed most advance technology (currently) and there is rather frequent firmware update when new features / radar guns are rolled out.

 

Passport 9500Ci & AL Priority. The cost to install is pricey, but nearly invisible unless you're looking for it. It has worked well for me, but you still need to use your eyes and mirrors too. Obviously I had laser jammers with the 9500Ci, but when I moved my rig to a new car, I learned the AL Priority jammers were the best at the time, so I upgraded. If I bought a new radar, I think the new Beltronics STiR Plus is marginally more sensitive than the Passport 9500 Ci.

 

The car I purchased had a Passport SRX already installed. I noticed that the rear detector wiring (license plate mount) were severed so I soldered everything up and then also slightly re-located the front laser diffusers to accommodate Zunsport bumper mesh.

Is the SRX to old tech to even matter?
