A number of other posts have covered the various bugs present in software release 014_013_030 including Comfort Turn Indicator option resetting itself to off and unpredictable trip computer resets etc.
The release promised by BMW mid last year has now become available as of mid March and has the designation 014_015_020
I had it installed yesterday and the bugs are gone. Don't know if there have been stability improvements in the Nav wifi connection etc but will report back once I have had a decent ride - probably tomorrow.
