It really depends on the combox you have, that will vary accordingly when your car was built.
If I am not wrong, all cars built after 09/2010 have the "correct" combox, and you should be able to code that. If it was built before that, you still could retrofit the combox with bluetooth audio streaming support.
Mine doesn't have the right combox, and didn't want to retorfit and code it. Then I found
this.
It solved the problem. If you (or your wife) use an Iphone and have Apple music, works perfectly. If not, works really well.
