I just bought the Blinc M1 bluetooth communication kit from a guy on ebay who also runs the site dakotamoto.com. So far, installation was fairly simple even tho my helmet only has the removable cheekpads, from what I gather some have fully removable liners?? Or I could be mistaken... Anyways, I've only used it for my main reason in the first place which is music, synced to my iphone, it works really well, loud and clear, just have to remember to turn off my lid after my ride now... I can report back on how well the phone function works, but its going to be a couple weeks, after taking my bike to work a few days ago in 65 mph winds ripping through the Coachella Valley, I'm waiting till April hopefully the wind dies down... That was the only time I've felt unsafe on my bike... Getting pushed around left and right, I thought I was gonna crash... :doh
