Sun glasses holder. INFO
 

I'm just spreading the word here, I am not affiliated with the seller in any way. If any user of the forum is looking for the accessory, may I suggest you look on a well known internet auction site. There is a main Volvo dealership in the UK which currently has these on offer at a ridiculously good price. I can only assume Volvo is shifting stock for previous models, trying to free up warehouse space.

Thanks for the heads up - bought one. Good price. There was a myvolvo offer on these but don't think it was that cheap
