The Whistler Pro 3450 has vg-2 and pop but you can't use both at the same time, would you run vg-2 or pop? I have readthat pop is hardly ever used but I really hope someone can tell me from experience. Also the installation says to mount the antena behind the bumper but the illistration shows it behind the grill?

 

Naw POP isnt really used in the U.S., or so ive heard. Im sure you will be fine without it.
