Earlier this week with IOS 12 released, 3rd party maps became available on CARPLAY. Google Maps released their Carplay compatible version the next day and Waze has a Beta going, expected to be released shortly. I feel a lot better with Google Maps being available, I have already swapped out Apple Maps on my CARPLAY Menu (you do this on your phone). A few times Apple Maps went into a recalc loop and it was just lame. Can't wait until they release the WAZE CARPLAY version too. I find that the CARPLAY interface is just so much better integrated.
