I know this is a audio thing, but just wanted to let rushmore street glide owners know, it didn't need to have the computer flashed at the dealership after install. It worked soon as I hooked everything up. My dealership wanted 1/2hr labor to flash it at a $100hr rate. Hope this helps someone.

 

Thank you, I just installed the J&M cable and borrowed my brothers helmet with speakers to try it out and it works fine. I'm getting speakers and mic to install in my helmet tomorrow.

 

I was glad to see that my headset worked as well, without a dealer flash. When I picked up the cable at my dealer's parts counter, I was told that it would need to be flashed. Not sure if it was just ignorance or an attempt to get me to have them install it, but the install was quick and easy as well, considering you have to remove the tank. This is one of my best additions to my SGS.
