Man! Riding with you is scary! Especially when you entered the highway near the beginning. I watched 5 minutes and can't take it any more.
On the Sena 20S, My three friends and I got ours in late June, four of the first 100 released in the US. As anxious as we were to upgrade from our 10R and SMH10s, I have to say that the 20Ss were not quite ready for prime time. All the features that you mention would be wonderful if the 20S would work more reliably. We lost intercom communication for no reason more often than not. The 20Ss would power themselves OFF randomly. The unit to mount isn't good, breaks or comes loose causing loss of electrical contacts. The Conference feature simply didn't work. Connecting more than two units was extremely confusing and unreliable.
BUT, when they did work, they were marvelous! The first thing we noticed was the total lack of wind noise when someone talked. We could even open the face of our modular helmets without transmitting wind noise. Fantastic! The phone feature works very well. People on the other end would say, "Really? You're really on your motorcycle?" Even at 80 mph on the Interstate, they couldn't tell.
I sure hope Sena gets these other annoyances fixed soon. We're going on another 5,000 mile trip in June and hope to have a better Sena experience.
