HALF HELMET INSTALL BEGINS AT THE 5:12 MARK IN THE VIDEO

I purchased the Sena 20S Dual Kit from Amazon.com Click this link for the item... http://amzn.to/2G1Cw7e. This was the cheapest place I could find them. I couldn't find much about installing this unit onto a half helmet. This will show how to do that. It was easy and took just a few minutes. The Sena 20S Motorcycle Bluetooth Communication System so far has met my expectations. Below is the link to purchase the dual kit.

After using a few times while riding, I still haven't tried the intercom feature. However, while talking on the phone while traveling at 70 mph, the person on the other end of the line said "it sounds like you are sitting in a quiet room". No wind or background noise at all!!!
