Do you think this has been done deliberately to boost sales of the Nav pro, as I'm sure this has the functionality to display the map on the AID or on both the AID and Infotainment screen at the same time ?
Maybe... but basically VW have never explained what NavPro can do over and above basic Nav. Its very frustrating.
Also, with the D variant hardware, suddenly basic Nav can do it.... no need for Navpro.
With the D variant hardware the Mk8 performs just like the Mk7.5 - with basic nav you can choose where the map is, with NavPro you (probably) can have the map up on both displays at once.
The sales literature for all of this is just as bad as it ever was with the Mk7.
I bought NavPro back in 2014 expecting to get Google earth maps, which I didn't because VW had silently deleted their licence with Google, together with never selling the connected version in the UK.
In 2017 I bought another NavPro equipped vehicle (more fool me really). It sort of worked as I expected, except for once again it didn't have its own network connection built in meaning that I had to pair it with my phone's wifi to get the VW live traffic.
It could have been worse, I could have had the slightly later Mk7.5 that DID have the built in Esim... the one that will be obsolete and useless at the end of 2022 because the 2G/3G networks it uses are being switched off. Possibly vehicles with that might not even get to the end of their 3 years of carnet service before that dies (eg TCR's)
And no Mk7.5x with the ecall emergency service will ever work after that switchoff. VW won't be replacing that unit with a 4G/5G one.
As with all of this technology these days, its life expectancy depends on network infrastructure that can and will be switched off at some point.
