Well I have had a string of electrical codes on my new 2017 Ultra limited that led to a dead battery and a ABS module replacement. During all of this the radio stopped working on several levels. First the sound quality went hollow, tinny, no mid-range is the best I can explain. Wife won't let me play the radio when she's on the bike because it is so bad, and she always has music playing. Then along with my other electrical issues the radio stared cutting out on long rides over 2 hours. And when is say cutting out, its more like you are slowly going further from a station and it progressively cuts out. But I am listening to SIRUS radio in the open. I have the latest software, the bike has been reset and three dealers have looked at the radio. Still nothing. GPS is working fine as are the other features. Drove on a long two weeks trip with hollow sounding radio. Came home, washed cloths and went for another week but left in the rain. In the overnight (while washing cloths ) the battery died and would not jump start, got another battery and was fine. Departed for second week in the rain and check engine light came on. Set 10-12 codes, mostly U codes. ECM replaced then ABS module. No codes after ABS replaced, meanwhile dealer called and original battery OK. Dealer says nothing wrong with radio?
