New member here but I get to be the first to announce a new Passport product!
Passport announced their new 9500ci remote radar that includes their new ZR4 shifters. Selling for $2000 installed if they are even really available. Other than stealth install it looks like it can ignore a false if you drive by one 3x without slowing down. I got this from a description at a site that is claiming to be selling them already.
ZR4s look a little smaller than ZR3s and are supposed to be better at LA detection. ZR4s alone look like they're selling for $600.
