I'm curious, Google is releasing a new split screen on Android auto, I think it's version 6.2. I don't have it yet but it's supposed to run 2 different screens 70/30 split. I think this may fix the issue we face on the stock 10 inch screen. Has anyone been able to get the new version yet and does it work?

 

Android Auto is designed by Google to fit a specific screen ratio, unfortunately it is not the same ratio that MB decided to use on their screen so it's never going to be a perfect fit.
