Hi all, I'm considering the HD hidden-in-the-fairing antenna for my '08 RG. The online site says only available in stores, so they don't have the directions available online as a PDF like they do for most stuff. Judging by the photo it looks like they provide enough antenna cable to run all the way from the stereo head unit to the back of the bike. (!?!) Does anyone know how these things install? Do they have you run that new cable all the way to the back of the bike and plug it in where the stock/whip antenna is located -- or what's up with all that wire, and what to do with it? If the antenna goes inside the fairing, it looks like the cable would be about 18" long, at most - - ? Thanks in advance for any explanations!
