I've started getting the enter user pin screen on my Columbus satnav in my 2018 Superb L&K It's never come up before and when I ignore it by touching the back symbol everything including updates seems to work without the pin being entered. 

Tbh I'm not sure it's satnav related and certainly don't have a user pin. I'm thinking it may be a code the garage puts in when resetting service info maybe 

Anyone got an idea what it is ? 

You need to unpair your phone from car, ( forget this device) and re pair.

Thanks Kenny R  hadn't considered it was my iPhone running iOS 13.1  that is causing the issue. Will unpairing  and then pairing again solve it ?

Great. Do you un pair at phone in settings/Bluetooth/devices or car ?

I unpaired using the car Bluetooth menu.

Thanks for all the posts and solutions. Re pairing did the job. 

This was caused by an iPhone update, I believe.

I have the same issue and have un-paired and re-paired using both the phone and car - but still the problem persists. Any ideas?
