I fiddled around with that.. but ended up getting an Interphone F5 bluetooth headset.. stereo speakers install to the helmet.. and I have it paired to an Ipod splitter (and my phone and a GPS when needed) .. plus the headset has a built in FM radio.. I live on a road that is a popular "ride" route and get aggravated at blasting steros (and overly loud pipes).. so I didn't want to contribute..
