Anyone else seen this? Set off yesterday and two navigation problems occurred.

(a) Navigation started, but on the dashboard display there was no blue-route shown. And while the navigation still worked in the route barrel on the right, the directions did not show up on the HUD (other information on the HUD, like speed, speed limits, etc, appeared as normal, it was just the navigation information that was missing).

On this photo you can see the dashboard -- the destination is shown with a flag on the map, and the route barrel shows navigation info, but you can see that there's no blue-route line on the map. You can also see that the route is set because the right hand side of the dashboard is showing the estimated time of arrival at the destination.

Here's a close up of the dashboard where it's very obvious there's no blue-route line.

(b) While this was happening, the map display on the centre console was not working correctly.

This photo shows.

i. There's no blue-route line on the map, despite navigation being active
ii. The vehicle location (the arrow) on the map is in the wrong place. By this I mean that the location is accurate, but the map itself should show the arrow in roughly the lower-left third of the display.
iii. The destination (flag) is way off to the right, and is hidden under the "No traffic notices along the route" information panel.

I was able to fix this problem by switching from navigation mode to the home screen (by pressing the button at the top left of the display) and then switching to navigation again, at which point the display showed the following:

which is correct (the car's arrow is in the lower left third, the destination flag is visible, and there's a blue-route line showing on the map).

The problem with the dashboard was not fixed by doing this. I also tried changing the dashboard display from "Map" and "Extended Map" to one of the other options, and then setting it back. This did not work either. I had to stop the car, shut everything down, and then start it again before the map on the dashboard and HUD started working properly again.
