Just placed my order for a 9500ix. I'm going to miss the arrows and Bogey Counter on the V1. I won't miss the many false alerts in town that makes me turn my V1 off, and then I forget to turn on when on the highway.
As a rule, I don't speed in town or on my way to work at the Hope Creek Nuclear Generating Station in Lower Alloway Creek New Jersey. The LACPD loves giving tickets to the nuke workers. The only time I speed is on the highway, and even then I go with the flow of traffic, with at least someone in front of me.
My main reason for getting a 9500ix is the installation of red light cameras in New Jersey. I suppose speed cameras are next. My V1, replaced once, has served me well for 14 years, and may still use it on long trips if I miss the arrows. With the advent of red light and speed cameras, I won't miss the V1, at least in town driving.
