There use to be a device out there that was called H-D BOMM. It would interface with your Zumo GPS and your Harley audio and allow you to speak using your headset through your smart phone while riding.. I know I know but it is hands free. I have one of these units and installed a few on friends bikes as well. They work very well. BUT the website now seems gone with no contact from what I can see. Anybody know what happened to this company?
