V1 all the way. I've been using one ever since Mike Valentine left Escort and created it. The arrows as well as the bogey counter are indispensable and after a short while you'll know just from the sounds what's up around you.

There was a period about 3 years ago when Valentine gave into the POP radar craze (he can be stubborn) and their first 2 attempts at it were a software flop. These have been resolved and the latest units work flawlessly.

I have 2 units, one that goes between the Boxster and the Cayenne, depending on which one is being used and another that stays in the Mazda since the wife uses it everyday to commute to work. One of the units is about 18 months old, the other is over 10 years old (it's been upgraded 3 times and patched once for the POP glitch).

BTW, the "upgrade" actually gets you a brand new unit for a fraction of the cost.
