Randall, in response to your three points:
1. Your reaction to the arrows is precisely what earned my friend a couple of tickets with his V1. He thought the arrows were showing him things they weren't, or can't. Results: busted, and he doesn't use it anymore.
2. This is wrong... the Passport
can be upgraded, and without sending it back. Uses a USB cable, and both the location database and the detector software (it's a software, DSP-based unit) can be upgraded.
3. The Passport has an "Expert" mode which allows you to track and display multiple bogeys across multiple bands.
Hey, I think the V1 is a good unit, you're just propagating bad info.
