Hello! (I am aware this was posted a while ago but hoping someone will reply!)
I am having the same issue with connecting my iPhone 7 to my 09/10 plate MK6 golf and am aware the bluetooth modules needs replacing.
I was wondering if when you replaced the module did it all work correctly with your headunit (I have the RCD510) and your steering wheel buttons?
I want to replace it but want to make sure everything will work as it should before spending that much money!
Also, does anyone know if there any different part numbered bluetooth modules you can install that work properly too?
Thanks!
