Anyone have an issue in their e-Golf with Apple Car Play volume being un-usable? When I try and increase the volume it sparatically jumps around, up and down. I can eventually find an acceptable volume but it's very frustrating. The seems to be with Apple Car Play only but I need to confirm it's not happening on the factory volume as well. I have an Iphone 10s and it happened on the 12.x version as well as the new 13.x IOS...
