Looking for the "Large" Full scr JVC file for EurNTU2017.20

Hi All,
I've been looking for the really large JVC file with Full screen photographic based Junction views and so far it seems without success. Firstly this is for Europe 2017.20 Unicode , but so far I've come across

Lane assist portrait full @ ~400Mb
Lane assist portrait med @ ~ 198Mb
Lane assist portrait Template @ ~ 255Mb
Lane assist portrait Android @ ~ 159Mb

However all of these appear to be too small for what I'm looking for


I've also seen a US-NTU2017.10 equivalent of what I believe I'm looking for at

CODE: SELECT ALL
Data JCV: length 866660352, name D3060200A.jcv
date 19.12.2015 16:43:17
006-D3060-20
picture size 480*270

so the file I believe I'm looking for should be in excess of 800Mb


anybody any ideas on location?. This is for a older Kenwood ICE unit (DNX7260BT)

BTW, I've tried the lane assist portrait full ( mentioned above @ 400Mb) , it doesn't work

thanks in advance
