2015 Streetglide special. When i plug in my iPod it plays just fine with the bike just sitting still but when I’m going down the road it will play then it keeps stopping and starting over and over. It’s a new iPod and cable. I’ve even tried Bluetooth too. . I tried switching to another iPod and it does the exact thing same. I’ve been thru all the setting on the radio and iPod. I don’t have a CB either. Navigation system is off. I’m going nuts trying to figure it out.
