We've had our SM10 bluetooth transmitter with our SMH10 headsets about a year. Last year after initial start-up issues. We had them paired and they would stay paired the entire riding season.
This year, I did the update just before using them and guess what? My helmet does not stay paired.:banghead::yikes: I have their 800 number from before and may need to contact them. It has failed the last 6 times or so. My wife's helmet pairs just fine!
I really like the system, but the pairing can be a "pain" when it doesn't work like it should.
If you find a remedy, please post it....I'll do the same. :thumbup:
I won't be working on it until we can ride again which will be at least a week based on our :cus: weather!
BTW: This youtube video might be helpful if you're new to pairing the SENA system: http://www.youtube.com/watch?v=9NKE0V78USs
