One week old 2018 EX and not happy with FM reception. Like others, see little value in Sirius/XM. Wondering if anyone knows if the fin can be replaced with a more traditional radio antenna for better reception.
2012-2016 oem antenna base (39152-T0A-A11) & antenna (39151-SWA-305) will fit and plug in just fine... I did the opposite for my wife's 2015 crv, she liked the look of the sharkfin. So we swapped the 2015 antenna for the 2018 sharkfin. As far as reception I can't say whether it made a difference or not, she doesn't travel out of town.
