Just did my update via the PDF. Followed the directions and also some of the other posts here that suggest the master reset (before and after). Confirmed install on SMR as 3.5.1 (from 3.2.2).
Observations: Soft Climate control is back and fully operational. I see the soft buttons as being A LOT more snappier. I'm not seeing the funky AM display that a couple of others saw.
I do recall seeing somewhere, I think maybe a post of the LA show of the Before and After screens where the After screen didn't show the compass and temp icons on the top bar. Both were still present on mine following the update.
LONG process. I did notice as I sat there watching the screens change that there was an MS Service Pack install too early on. As I've always said (and others have disagreed) MS is the main issue with this system. I'm glad to see them working on it though with the service pack.
