I have to second 2Lanes opinion here
I have had the 2820 for a while.... and a bluetooth phone... on the way out the door to Nelson i bought a Scala Rider set up.
It worked, more or less but probably more due to my cheap helmet than anything i couldn't hear the phone audio very well, the nav audio was ok and i could get by. It is an easy to use piece of equipment but it does hang off the side of the helmet.... i think it would work much better on a good helmet as opposed to my 30 dollar flip front. a good entry piece for those who want to dabble in the bluetooth thing without investing in a new helmet ( PM Me)
after much discussion with a number of folks here i invested in the Nolan bluetooth rig. I had a few glitches getting it hooked up, and got to use it this weekend for the 1st time on the road...
It is amazing! I am very glad i bought it, phone calls are quite clear and mostly folks cant tell im on the bike. Don is absolutely correct about the functions of the 2820, and i use them every day either in the truck or on the bike.
the audio in the helmet may not come through in stereo, but it has plenty of volume!!!! and for theose keeping score, no i didnt buy the matching helmet color to Dons LOL
