hey guys i bought a beltronic stri driver radar detector, sadly it is not working as i hoped it would be. i live in the bay area, i drove pass police cars many times, and my RD doesn't really alarm me at all !!! and yes it detects those useless speed checks and crap. what are some of the other RD that can detect police around my car? my friend said he saw a RD onces on a magazine that can tell you the numbers of police cars around it... is that true?
