Needing some help re VW Golf updates

Hi Peter,
Thank you for your good wishes, however I didn't get much sleep. Well I managed to download and install the latest maps overnight via discover care manager but unfortunately all I get is a message saying "The navigation data in the infotainment system are not valid. Please check data."
If I now go into System Information it says:

Device Part number 5G0035846
Software 0142
Navigation Database
5G0919866BC0057 ROW 2020

I'm beginning to wonder if this is a software problem (needing updating) rather than a map update.

I have attached some pics to show you what I mean. Including one of the unit itself which is a Discover Pro I suspect even though Device Part number 5G0035846. Which I believe represents Discover Media???

Cheers for now Greg.
