My new 06 Civic EX sedan developed poor radio reception not long after we got it. AM and FM radio reception is terrible compared to other vehicle in same location. AM radio will crackle & pop and the volume goes up and down while driving over a bumpy road. Dealership told me they have no service bulletins, but they did admit that they've replaced the rear window for one other 06 Civic owner with same complaint. They said it "fixed" the problem. Because of another problem, I've already had the speed sensor replaced on this new car and that didn't help the radio reception. (I thought maybe the SVC 'speed volume control' was messed up because of the faulty speed sensor). I am worried about what can go wrong if I get my window replaced, eg. leaks, damage. I think there is a bad connection somehwere, rather than a bad antenna inside the window glass. I've read Pablo's message tree from Feb. '06 re. his AM radio reception, but I can't find out if anything was resolved there. Anyone else with this problem or anyone have any ideas what it might be? Thanks. K.
