I've got a Kenwood marine grade deck with the Biketronics Retro Radio adapter. When I hit a bump, my music stops playing. When I'm listening to stored music from my phone through the blue tooth, it switches over to the USB chip. When I leave it on the USB and hit a bump, sometimes it just stops altogether. That makes me think it's something to do with the deck. I've had the fairing off, and everything is snug and connected. Bike is an 05. Looking for ideas before I dump this deck and look for another one. Thanks.
