I seem to only get this when pulling out of the car park after dropping my daughter off at school.

Anyone else seen this ?

It pops up for about 30ish seconds then disappears again.

 

 

I'd normally only expect that when crossing borders 🤔

That might explain it then actually,  the car park would be "off road" so when leaving it I am effectively entering the UK again

Unless you live on the Irish/Northern Ireland border, that is probably not going to happen.  Suggest updating the maps as well as the firmware of the MIB2 radio itself.

Some versions of the Octy were built with a hidden air sensor, it can detect strong odours such as soft cheese and garlic, perhaps this is triggering the cross-border software.  

I get this every time I drive on a specific section of road near my workplace, that's relatively new. Wonder if the car navigation thinks I'm rejoining the road at that point?

Is the road near your daughters school new?
