Didn't work - well, I think it worked one time, after the re-install AND a reset on the phone's Customize Carplay settings, and when I exited Waze and went back in, it was dark again. I've also found news apps in Carplay that I didn't ask for, and the order of the apps has changed, so that all of my three navigation apps are no longer in the first 8 apps that appear. I've gone into Carplay settings on my phone and was able to delete some, but not all, of the new apps, and while the menu tantalized me with the suggestion that I could "organize" the apps in the Carplay home screen, I could not see how to do that. I know I've read some instructions about organizing the Carplay screen. During the course of this work, I also managed to discover that the screen was set to "Always Dark" in the Carplay settings, instead of "Auto". Playing with that, I managed to get the screens in both Maps and Google Maps to be dark, where they were previously light.
