Pricing depends on the whole set up (i.e. jammers, etc) Where are you located? I am in CT and i can give you the place where I had my friend's installed. The installer said he just had a customer flat bed 5 cars to his shop (from NJ) to have them all installled with the V1 and jammers (3 Ferraris and a couple of Porsches).

The detector itself is hidden (location depends on the car he is doing).

It is the coolest thing i have seen it a while.
