Yup - just had a quick look in the garage, and my HUD shows the same when parked, even with a destination programmed. The virtual cockpit display in the speedo does have directions, though. (Wouldn't be much help posting a picture here, as at the moment it only shows an arrow and "off road").
When I'm on the move, the nav shows in the HUD direction and turn arrows, street names** and (so far) pretty good lane guidance. The HUD also shows if there's a junction or two before my turn, and marks mine with a blue arrow. It's possibly not as "flash" as the Q4 system, but it's certainly a step up from the system I had n my 2015 A8. The green early warning "slow down" symbols for junctions, roundabouts and roadworks seem to work well enough. I think that's part of the "predictive assist" system. Still learning from the book!
**Here's a note and a question. Recently, the street name in the HUD "flickers" a lot, most especially if a road has a name and a number. It seems as if the nav can't decide whether to show the local or trunk name for a road, and it's very irritating. I'm not sure if there's been an update that's started this behaviour, as I had not noticed it before about a week ago (ish). Has anyone else seen this?
