Map is normally stored on built in hard drive but you can also temporarily read a different map from DVD. Map on hard drive is routinely updated from DVD but there is also a back door to update from SD card as older units can struggle to read non-original home burnt dual layer DVDs readily available on eBay (search map update for RNS510, the VW badged version of this generation of Columbus)

Your local Skoda stealer can supply map disks but recall reading list price is around £200.  eBay going rate is currently less than 20 quid for the normal DVD option.  V17 is latest map version (released almost 3 years ago from recollection, then used to release yearly(ish) updates, guess likely the last update as these systems were I believe first released mid 00's). Bought my last 3 updates from this chap - https://www.ebay.co.uk/itm/124780880293.  That listing also includes firmware update disk if you need it.  Sure he can provide just the map update for cheaper if that's all you need, he's very helpful and can provide any tech support you need.

VW RNS510 West Europe v17 2020

 

I do have this, 99% sure it's the last ever release, probably needs firmware update too as "base" for the map to sit upon.
