Sport Gen 2.1 InControl Touch Plus Europe - 2020 map update?

Range rover sport l320 petrol 5ltr 2011 auto.
I was looking at updating my satnav I see the 2012 model can have a memory stick update of the Gen 2.1 InControl Touch Plus Europe - 2020 map, Question I have is, how do i find what Gen my satnav is on my Range rover? is it in one of the info pages on the infotainment screens? or do I have to manually dig under the passengers seat and extract what i need from there? I believe I have the denso type system. Any help would be good as I'm getting old and disabled so getting under the seat is a hours job for me. but I still like to potter around.
Thank you.
Ps was planning on full update to apple play guy on Facebook fits these but if i can just update the satnav to 2020/21 I will be happy.

2020? still 2 years out of date for Europe.

Nice leather colour.

Looks like a apple play unit then, at least I will get the latest maps, anyone had these particular units fitted? I’ve heard some good things about them. Thank you Datatek, and yes we like the leather, was a bit unsure at the start but it’s not overwhelming.
