I recently took my Sportster car kit out of my car to use in another car. I just put it back in my original car this weekend and now I can't get as good of a signal as I got before. I got 3 bars no problem before, now I only get 1. Every once in a while, it will jump to 3 but most of the time it is only 1 bar. Do I need to do something to re-calibrate it or something?
