I currently own the Sena SMH 10 and absolutely love it. However, a lot of riders such as myself ride solo and don't use or need the intercom feature. I only use it to connect to my iPhone. My suggestion is to add a "disable intercom" feature in the set-up menu which could then free up some of the jog dial/ phone button combinations for other uses such as being able to end a phone call by just intuitively tapping either the jog dial or phone button (currently you have to remember to hold the jog dial for 2 seconds which can be confusing.) Anything that gives you more options of just using the jog dial vs. having to fumble to find the phone button while wearing thick gloves would make things easier.
Just a thought.
