Uconnect Software / Firmware Updates? I saw the other day that the 2016 Uconnect 8.4 has got a long list of really nice new features that I would love to have on my 2015 Uconnect 8.4, mainly a button to see the reverse cam at anytime, and SXM holding up to an hour of music on each of the stations saved in your favorites. I'm hoping Uconnect will release these features in an update for the older models since it seems to be the exact same hardware, but is that the case? Have the older 2013 & 2014 Uconnect 8.4's received updates to bring them features that came in 2015? Or am I going to have to look into alternative means for getting the updated features on my 2015 Uconnect?
