So here's a weird issue with Apple Maps...
On my fully updated iPhone 11, when my phone goes into dark mode in the evening, my Apple Maps show up dark, as it should. So do Google Maps. No issues there.
On CarPlay, in dark mode, the top information bar showing the route/lanes/turning directions shows up in black (as it should in dark mode) and the bottom information bar arrival time/travel time/distance shows up in black (as it should in dark mode). But the actual MAP itself is still in "light mode."
Google Maps renders in CarPlay as it should
I've tried this in two different CarPlay settings - my own Coral Vision CarPlay tablet as well as my wife's OEM Toyota Rav4 CarPlay head unit. It displays the same in both, making me think it's something particular to my phone setup or a very weird bug.
My wife's XR renders the dark maps in dark mode as it should, on her phone and in CarPlay.
Any advice welcome.
Updating on my own post...
This is definitely a "my phone" issue as my work gave us the go-ahead to update our work iPhones to iOS15, and my work phone (an XR) correctly shows the night/dark mode version of Apple Maps on CarPlay.
My personal phone is an iPhone 11. Wondering if it's a bug specific to that model of phone or whether it's a bug that's just randomly showing itself on my iPhone and no one else's.
Trying to Google a solution to this is near impossible, as people end up telling you to turn down the brightness on your screen/dash to kick Apple Maps into dark/night mode. But, as noted, I can swap my phone for my work phone in my car with nothing else changed, and my work phone goes into Maps dark mode perfectly on CarPlay.
I really don't want to nuke my iPhone settings and set up my phone again in the hopes that doing so would fix this issue.
But given Edmonton is dark ALL THE TIME NOW in winter, I'm basically using Google Maps in my car because otherwise I have this GIANT WHITE GLOWING RECTANGLE of mapping in my car while driving to and from work in the dark. And yet, Apple Maps on my *phone* goes into dark/night mode exactly as it should when I toggle dark mode off and on. It just won't do it on CarPlay.
