Think my radio is toast! Bought 2013 RTL in March with 14k miles, everything worked great. Few cosmetic blemishes but all's good. Have ridden bike now for 4+ months 2200 miles, things are starting to show. About 1 month ago radio stopped working on a ride, went to mode setting for audio, was locked to "XM". Shut bike down, restarted, radio is good, finish ride. Since then the radio has worked intermittently, 2 minutes on then silence, now can't even change out of "XM" mode in audio selection. Controls work for all other functions and such. Disconnected battery, and plugs on radio (under right side hand grip), still same after reconnected. New radio $550+. Any suggestions from the forum?
