Passport 9500 is the one with GPS technology to reduce false alarms? I'm not
that big into this technology --- what if a police car lies in wait where
the false alarm is?
The V1 gives source counts, which lets you know if a police car is in the
same spot as a false alarm. Of course, this is only helpful if you're
familiar with the route and know where the false alarms are. | c****i
