I finally got my V1 hardwired in, still have the concealed display to do.
Took my daughter home through Liverpool in the UK and got an instant full alert on laser. About half a mile down the road I saw a police CCTV van just moving off from the road side. These are known to carry laser, in the UK they zap your number plate and do an instant check to make sure you have road tax, insurance etc etc. Not sure if they also pick speed up or not.
Anyway, the V1 picked it up great and the pick up must have been just laser scatter from a hit on a car further down the traffic. So, I'm impressed already.
