  • Hello,
    The setup and car button do not work for the Hidden Green Menu. Is states that there are no other options. I saw that in other sites that it need to be programmed to be able to work, so I can enable it.
    I have asked Audi dealer and the local auto systems store and they know nothing about it. Please tell me what devise is the one I need and where can I buy it. Thank you in advanced

    • Yeah, green menu needs to be enabled (if it’s not already). Browse through the MMI 3G tutorials and you’ll find instruction how to enable it.
