Picked mine up today, which was a wonderful experience (will post some pics later), but one thing really bugged me on the way home:
Couldn't find how to adjust the volume of alerts and navigation commands. It's also not clear from a quick look through the manual. Volume button has no effect whether or not the media is on and I can't find anything on either screen menu :?

Sorted. Thanks a lot fellow ultimate blacker! Easy when you know how isn't it? I'd been trying the steering wheel volume control!
