Today I got from the Sena facebook promotion a free SMH10!
It allows me to connect a walkie talkie to the bluetooth system in the helmet! This gives me more autonomy to talk further (up to 16kms depending on the walkie talkie) and I can talk to a car with a wlkie talkie! not bad!!!
I´ll have to test it after the walkie talkies arrive with the move though..... a post to come!
