I just had the Sena Dongles with cable, and my Garmen 660 GPS installed on my 2013 Vision by the dealer. However, I do not hear the radio with my Sena headset. I do hear my GPS instructions and music in the headset. I have tried turning the bike off and removing the GPS from the cradle, but still am unable to hear the factory radio. After browsing the various forums, I see that some of the Victory bikes had to have the radio "flashed". Could that be the case with my bike? Is this something that I can do, or must I take the bike back do the dealer?
