ive used passport and V1, if you dont get a V1 your just wasting your money

 

yeah, V1 is great. If you have bux though, get the bel sti Driver. thing is the shyt! Has a magnesium casing, so even if cops are using their radar detector detectors they can't pick it up as opposed to the vg-2 technology which basically shuts off your detector, so no help there
