where do you live that VW doesn’t support car play or did they drop support? My last two vws going back to 2017 in the US support it and so have vws i’ve rented in Spain.
Do you have the basic media unit that doesn't do anything or what? Otherwise you can just google the instructions to update and unlock your unit's features for free. Most MIB2(.5) units can easily be hacked.
It ain’t MIB2, or MIB - rather some ancient POS that runs android 6 and doesn’t even have a USB port. It’s just… Iberia, I guess. They know they can get away with getting rid of crap old stock here and people will accept it as the shiny new thing.
