I am using it. I have had it for about a year or a little longer. Works great. I have ridden through days of torrential downpours and it never quit working even being mounted where it takes on all the rain. When I use it on the Concours, I have it run through an amp and to my helmet speakers. When I use it on the Vstar, I run it through an amp and through bar mounted speakers. On either bike I can hear it very clearly at any speed. Easy to read and use the buttons with gloves on. And nice to be able to plug MP3 or iPod into the auxillary plug as well. The only complaint I have about it is that I can't get the backlight to ever go off. On the Concours I have a switch to cut power to it. On the Vstar I don't and after about a week of not riding the Star, the backlight on the Jensen will run the bike's battery down. I have read the manual and it does not say anywhere how to power down the backlight.
Also get a good antenna. The gentleman I bought mine from threw in the antenna and the mount he had made. I pick up radio stations as if I were in the stations parking lot.
