This is listed on EBay and lists VW T Cross as able to be fitted to. Not got it on mine but looks like it's doable, at a price though compared to my next base 412g but that's forward facing only. https://www.ebay.co.uk/itm/223683268035
I have also used nextbase duo hd for a number of years and it is easy to move between cars if required The evidence from it has been used in a successful insurance claim. I like the look of the VW system but cost counts against it compared to what I'm currently using..
