I'm sure a lot of you folks know by now, but just wanted to confirm that the new Coolwalk enhancement for Android Auto is working brilliantly, at least on my 50 TPP. Google Maps can now span across the entire screen!
If you're in AA and you have the option to expand Google maps to full screen, then you might already have Coolwalk enabled. Another quick way to visually tell is if the 4 corners of the Google maps tile are rounded vs. the old 90 degree sharp corners, then you have coolwalk enabled.
