Must have had an OTA update as yesterday when starting the car the 3 main widgets had changed to default, there were only 2 icons at the bottom of the screen, the others were + signs and my saved radio stations were all gone. I was still primary user though and everything connected (phone, wifi hotspot, android auto etc.) and all worked fine. I'm on 1940 btw.
Had a look and the only thing I can see is that the navigation database has changed from 23.6 to 23.7. I've had to put everything back to how I want it on the infotainment screen, no big deal but a but odd don't you think?
