I have a GC 680 on order and didn't bother ordering the Toilet Ventilation SOG as an extra because I assumed it was simply a fan fitted in the roof vent of the wet room. Recently I googled 'toilet ventilation SOG' and found a website which explained what the system was. I was totally surprised how the system works and apart from reducing 'odour' it is environmentally friendly and can be used without the need for chemical additives, which a growing number of smaller UK sites are no longer permitting. I couldn't find any details of the system on the VW website. Fortunately, I have been able to amend my order to include the system!
