Updating database

[MrBitsy]

Online flying with VATSIM is going to need an up to date database.  In the product description it is stated there is no current plan to update the database.  I do have a Garmin Pilot subscription, so does the functionality exist to use this subscription to update the database?  Having an old database means no purchase for me, but buying the product is a no brainer if my Garmin Pilot subscription can be used to keep the product updated.

I live in the UK.  I just watched a YouTube presentation where no charts were available for EGLL - is UK data in the product?
