I have a RGU 16. Not sure if I have a short in intercom system. I do not like the VOX system, so I just set it all the way to the right when riding, so I can talk to the wife. The system can be working great, we can stop, shut off the system, start up again on our ride, and not one of us can hear, the other cannot. Sometimes jiggling the cord helps, but it is frustrating, plus, I hate the cord. Thinking about the Sena 20S. It sounds like I can talk to my passenger, play music through I phone, get phone calls, listen to FM radio, and somehow hook up to GPS. Plus, no fricken cord. Anyone out there use this system, instead of the infotainment system on their glide, when wearing a brain bucket. Thanks.
