Yeah I tried going through the Z4 menu, no luck there either. I'm thinking the head unit used in the '22 is a different unit than previous years because when installing the bimmertech MMI, I followed the video instructions and noticed the cables and ports on the back are pretty different. Still...
Has anyone been able to successfully code the AUX Audio on a '22? I went the bimmercode route but it doesn't allow me to go through the head unit settings. Gives me a message that I should try updating but my app is fully up to date.
