It works fine but it can be better.
First of is that you can't make Android Auto to go Automatically Dark Mode at night no matter what settings you put into Android Auto on your phone, it would be easy for Andream to set this right because MMI Box have access to the CAN Network of car and the MMI Box could send signal to Android Auto that Headlights are ON and Android Auto would change to Dark Mode like OEM. Heck not even Waze goes Dark Mode at night and Waze have a setting to only go Dark Mode at night but for some reason the MMI Box is forcing Light Mode, you can only switch to dark mode if you change it manually which is not that fancy to mess around.
You can't change DPI for Android Auto in MMI settings and this would lead for a better image quality and more information on Android Auto but instead you get somewhat bigger UI that takes lots of the screen space. I have the Dynaudio Premium Sound with Discover Pro MIB1 7" Display System.
It took awhile to set the Audio and Steering Wheel Controls correctly because using Car's BT Audio Channel was not working great for instance map alerts and Google Assistant were very low volume everytime they speak even if you adjust the volume when they do speak it would default to low volume again, started to use AUX and it was much better in fact in MMI settings you could adjust Music alerts etc volume independently when AUX is in use.
Another minor thing is that when you start the car and do Reverse gear before Android Auto begins in between you start hearing the music playing meaning that Android Auto is already Active but after you finish Reverse you will not get automatically to the Android Auto screen you will have to press manually to go to, anyway this is fast enough to not bother much but still.
Andream Support is OK but I didn't get anything helpful from reporting this issues.
Wish I could have some insight about future MMI Box software updates, like on what they are working on to fix or add to the MMI Box.
Make no mistake this is a High Quality MMI Box and it feels like it from the MMI Box UI to the Actual Carplay/Android Auto experience the modern look and easy of use when you get the grip of it.
I would give 5 stars if it wasn't the things I mentioned that are deal break.

all the products tested and purchased in this shop are of good manufacture I am a professional and I only install the products chosen by Andream
