Pics of the ZR-3 instal....
You don't need a radar with it...but only detects and scrambles laser....in my opinion you should use it with a radar....the good thing about the passport 8500 is that they both can be "integrated"!
You (in theory) can only buy it from authorized dealers....istallation is included....check the website!

What is actually worse than radar and laser are the fixed installations. They don't use radar nor laser, but use sensors that are build into the road. Only GPS can help out to detect these buggers !
