I have used the Valentine every since it came out I am sure it saved me many times. I bought a new Passport with GPS for the Mustang seems to be working pretty well. I rather have one than not have one.
Yea, I've heard good things about the 9500ix. GPS marks known speed traps and cameras, and you can upload them from an online database. Weeds out false positives too. See someone get nailed, you can mark the spot and it will warn you next time.
Since the switch from the Valentine, have you noticed a reduction in false positives?
