Vehicle went back in for a check on the 24th after owning for a week. Initially I had no reversing camera then when I got to my destination and started up again I had no screens working inside the vehicle at all. Vehicle drove fine however, was driving blind so to speak.
Local VW dealer advise VW have released a software update to fix these issues and that they are supposed to have communicated to owners of this.
Software update successful on 27th and awaiting full testing by the garage on a full charge.
Blank screens and no reversing camera
I have had the blank screen with the reversing camera image a couple of times, both with the original 0564 software and the 0570 patches. Reported it to VW ahead of them attempting the 0783 updates in early January.
