Only thing I have noticed that changed on mine is the intercom. I can't hear myself when I speak. But it is clearer and no wind noise. My wife says it's much better. I also can't hear myself when on the phone. Kinda make me feel like I need to talk louder than normal.
Also the zoom feature in the nav and weather map works like it's supposed too now.
I noticed the same things, wife didn't like not hearing herself at first. Haven't used the phone yet. Did have a new issue pop up and that was the whole Boombox locked up downtown San Antonio trying to get to the hotel, GPS display froze, kept playing music but could not get it to respond to any input, nor could I turn it off. Everything was fine after shutting bike off and turning back on.
Only other thing I noticed was it seemed it took a long time to sync bluetooth with my phone. Oh well fix one break another.
