We have both. The V1 in the M3 (wife's) and the Passport in the Chevy (mine). We both have been saved numerous times. But, I hate listening to the V1 sqwauk all the time where my 9500iX is silent. Yeah, we can reach up and push the silence button, but why bother??? I do like the arrrows and kowing how many radars are being detected via the V1. But, it's more important for me knowing where the redlight and speed cameras are before I get to the intersection (9500iX).
V1 with the GPS would be the bomb. But, until then, I'll keep the 9500iX.
