Just traded in my 2012 RT-S for a 2018 RT-L Chrome and noticed that the FM radio reception was, for lack of a better term, was crappy. It couldn't really get any local radio stations at all without static. I did notice that the antenna on the rear was a shorty type antenna. I am not sure if this is stock or aftermarket. Is the FM reception a known issue with this year RT-L or should I be looking for a possible disconnected plug or chaffed wire>

thanks in advance
