Because so many of these nits are occasional/situational, there's a lot of hopeful but inaccurate 4.4 reporting here:
1) Map day/night caching issue is NOT fixed. It IS intermittent, so may appear to be fixed for a while, but then you'll get it again.
2) Energy consumption while parked appears the same. I agree with the poster who says perceived differences could be weather moderation.
3) There's no difference in the backup camera performance.
4) The issue of blank left dash screen after navigation is not new (tho some seem to be experiencing for first time), nor is it fixed.
etc.
My suggestion to all posters: don't post something as a new bug or behavior until you've done a search on it. Don't post something as fixed/changed until you've verified or measured it several times. Whenever we get new releases, we all seem to notice stuff for the first time that may have nothing to do with the release, but rather our perception.
I'm telling you though, the hovercraft suspension setting really IS great, used it again today.
