The v1 has PoP AND it's upgradeable when new features come out. I just had my V1 upgraded to the latest greatest firmware/options for $75. With any other brand i'ld be looking at purchaseing a new unit.
"7. In my eyes, arrows don't do jack. You'll know where the cop is...big deal. Bottom line- you have to slow down"
The arrows are what sold me on getting 1. Once you have the arrows you wonder how you ever lived without them
LOL! Knowing of the cop is behind you, to the side or in front of you is a good thing. Take for example : Detector shows radar to the front, it's at night and you can't the cop. when you pass the cop (doing the limit of course) you can see that you've passed him because the arrows will show radar to the sides and to the rear once you've gone by.
