Virtual Cockpit VW Golf7

[eprst]

Hello. There are several options for virtual dashboard for VW Golf7
5G1920791, 5G1920791A, 5G1920791B - with NAVI
5G1920790 (A,B) - without NAVI
5G1920794 (A,B) - without NAVI
if I'm wrong - correct me
Has anyone tried changing the firmware?
Dashboard - 790.794 to 791fw
The difference is only in the firmware? or are there differences in the boards?
does anyone have firmware 5G1920791, 5G1920791A, 5G1920791B?
