I believe the reason you only have a problem with the intercom and not the radio is because the culprit is the SM10 transmitter. It is over-riding the intercom (it's not supposed to ever over-ride the intercom or gps). Turn the SM10 off and the intercom distortion will go away...at least that's the way it is with mine. The SM10 (the dongle as CanAm calls it) transmits the radio perfectly to the headsets...then when you switch the headsets to intercom, the SM10 signal (carrying the radio) is supposed to be muted. That's what's not working right (I believe for all of us). Try it and see. Turn off the SM10 and just use the intercom. I'll bet you will not have any distortion in your intercom.
Here's the rub, now with the SM10 turned off, if you want to listen to the radio in your headsets, then you have to stop...get off the bike...get to the SM10 (open trunk... remove suitcase... unzip inner lining...turn it back on...put everything back in place...get back on bike...and don't use the intercom. That's NOT the way the system was designed (or advertised) to work.
And another problem: not only will the SM10 distort the intercom but it will also distort gps and phone audio. If you use your phone bluetoothed through your GPS to helmet, the SM10 will over-ride (distort) phone calls as well and GPS audio (direction prompts) the same way it distorts intercom (intermittent). I've lost many a phone call because of this. When it works right, it's a super cool feature! But it screws up often.
Sena and BRP should make this right with all of us who shelled out the bucks for this system.
Sena has another model (SM20) that I am told is a little more advanced than the 10's. I'm interested to know if the 20's have the same problem.
If you ride alone, obviously you will not have had your intercom interupted with distortion... (you wouldn't be using intercom riding alone

but you can have phone and gps distortion...if you use those features.
I want my system to work right.
