Hi, Not a great start to GTD ownership ! In my experience the voice function only works if you have specified voice control as a specific option ? The radio and phone presets being lost is a strange one and I think may be related to the driving mode selection being unavailable, try another reset or clean the radio fascia as static can build up and render the screen unresponsive😡. When the driving mode won't change from the switch it usually will from the touchscreen , if all else fails get it booked into a VW dealer and I'm sure u will get it sorted out, cheers .
