The rest of the comments are noteworthy and I'll play around with it when I finally get around to driving it on a long trip in a week and a half. I might try the Tomtom on the way up and Googlemaps on the way back. I do like Android auto, the 3D googlemaps resolution looks great on the 12 inch screen.
The reason I wondered about the seats was I realised after comments on here it was hidden in a submenu. Just maybe just it could have been a factory extra that motorpoint never declared. Back in 2016 I got a 500x off motorpoint advertised with no extras. When I saw the car it had a spare wheel and "comfort pack". Then on the drive home I saw these yellow lights in the mirrors and audible lane warnings and found out it had the £1,000 safety package with things like lane assist and reversing across in the car park thing the C5X has. Lovely jubbly!

The boot mat I got from Ebay from these people below. Pops up at £50 but then when I clicked through it was £45 inc delivery. There seems to be a few suppliers around the same price. They are £80.72 excl delivery on the citroen website.

It came rolled up a bit but they soon go back to flat.
I'm just waiting for the car mats now, I hope they are good ones. At an advertised 2850g per M2 I'm hoping they are.
