Ok so i picked up a new Passport 8500 x50 from pepboys about 2 days ago (employee discount or i would've went elsewere). I went up to north jersey in my dad's 2008 jeep wrangler sahara and figured id set it up and just test it to see if it worked. on the way up and back on the highway id say we passed 4 cops. 2 state troopers sitting in the median facing perpendicular to the highway, 1 driving on the opposite side of the highway, and 1 unmarked car coming from behind me and passing me. Is it possible that all of these cops didnt have radar on? I've also went by cops pulling people over (about 2) and no signal. I've only gotten weak-mid K band signals and thing this might be malfunctioning. I've reset it to factory settings and am still in the testing phase. Never had one of these before and will be using it on my 2002 camaro ss. Any help is appreciated.
