Navigation Database Unavailable

[AdamInKent]

Hi all.
I had a new (for me) MMI fault this evening. On the journey out, I used the built in navigation and everything worked normally. On the way back, on switching on the car, I got a “Navigation Database Unavailable” message in all the navigation screens. Thank goodness for Apple CarPlay (first time I’ve needed to use it). Has anyone else had this? Have you worked out the trigger?

I had it once, and a few mins after MMI locked up and dash etc all rebooted then started working again. No idea what caused it.

The only time I've had that was when the dealer rebooted my car and didn't load the new software up in stages which meant I lost all connected services, maps and cruise control.

Never had that without the dealer instigating it though...

24 hours later and the fault has not cleared. I am beginning to wonder if the map data has been corrupted. (Perhaps coincidentally I am also not able to access the online manuals.)

I’m not impressed with either the Roadside Assistance or Audi Digital Support helplines, neither of which appears to be picking up the phone. I’ve sent an email to the latter, who have responded that there may be a delay due to high demand.

Can anyone please point me towards the instructions for rebooting the MMI or reloading the maps?

DJAlix on here is the man to contact & sort you out.

Can you not just do a factory reset?

I have had this problem for months actually but never paid any attention to it because I thought the car recognized when there was an Apple Carplay Phone connected and favored this system over it's own. I've not had any of the dreaded MMI issues other than this so I'm a bit reluctant to take it to the dealer for them to try and update or reset in case it changes the firmware version. Will be following this with interest.

When I got into the car this afternoon, the fault had cleared itself and the sat nav was back to normal. (Or Audi Digital fixed it without replying to my email?) Slightly annoyingly, it was after I’d bought a new USB A/USB C Memory stick to upload the map database, on the assumption that it had somehow corrupted.

Hopefully it’s a one off. One final note of interest: when I drove the car yesterday, whilst the fault was still showing, the car was able to give verbal navigation instructions, even whilst not being able to show any maps, after I’d sent my destination from the My Audi app on my phone. Which would suggest that the maps were still there, but for some reason the car couldn’t display them?

I downloaded the map off myAudi and put it on the USB stick and plugged it in. Got to 5% and then said there was a fault and it cancelled the installation. Tried it numerous times and done a factory reset to no avail

Did you get this sorted by any chance?

Mine's doing the same thing (21reg TfSi e). I haven't tried to update maps via USB yet, but if it did work, I may give it a try.

Just to add to this, I had a service at Watford Audi who were unable to fix the issue. It apparently needs a software update, which isn't available at the moment.

That’s strange, I had this issue that wouldn’t resolve itself, amongst a few others.

it was fixed when my software got updated to version 3620.
