i use a sony marine grade, as already stated hd-dude can you you a mounting kit and harness adapter
I used the Sony marine also as recommended by Jim. Sound is so much better it is amazing. But I'm on my second and now it has gone bad. Since the first one is sitting here, just back from Sony warranty repair, I was going to switch them out and send the second one in for repair but this is becoming a PITA. When I sent the first one in, since the radio was pretty cheap, I bought another and just figured I'd get the first one back and have for a spare. The Sony warranty rep. called and told me it was moisture damage and that was not covered by warranty, I went off on him, as this was a Marine Radio and moisture issues were not covered by warranty?

I asked for his supervisor and got a much better response, it was covered.
Point is I was much more careful when washing the bike with the second Sony and now I'm in the same situation. I can only assume it is due to condensation inside the fairing or due to the harness. Anyway before I reinstall the first Sony and send the second in for warranty service, I would like to know what is causing it.
Anyone else had this problem with the Sony?
