Adding a bluetooth headset to your helmet is both easy and fairly cheap. They add the ability to pipe turn by turn navigation from your GPS right into your helmet. You can also talk with your buddies when your gas light comes on, when you're looking for a bite to eat, or need to stop for any reason, is well worth it. Comm systems really cut down on the hand-signal tomfoolery we’ve all experienced on the side of the road. The Sena SMH 10 though not as fancy as some newer models, remains a very good, reliable workhorse in this area, and they’re relatively inexpensive these days. We recommend the Sena or Cardo as our favorite brands.
