OK, I've seen the jammer results and am looking to buy a jammer for my grey 2002 Mustang GT. I will be pairing it with an X50. What is the best jammers currently available? Would the ZR3 or the BEL 905 be the best choice for integration with the X50? I drive around Cleveland, OH and Detroit, MI and Atlanta, GA often and was wondering if these jammers will be sufficient for these areas. I'm still a newb when it comes to decifering all of the test info and threads here.
