The wife rides a 2011 Limited. She was on her second radio when the speakers would shut off while listening to the radio/IPOD. She found that if she turned the speaker switch back and forth, the speakers would come back on. We took the bike to High Country Harley and they experienced the same problem while test driving the bike. They called Harley and was given a whole laundry list of things to do to ensure this radio was not bad also. After doing what Harley desired, High Country put in a new radio at Harley's expense and drove the bike about 40 miles with no problems. When we picked it up last night, High Country told us they had just received a call from from another Ultra customer with the exact same issue.
So far, the wife has not experienced the problems she was having and is very happy with the new radio and High Country Harley.
