iPhone 15 Pro Max, 2019 BMW and CarPlay works better than it ever has. Much more responsive, connects faster than with my iPhone 11 pro. Connects thru Bluetooth or cable. Just throwing this out there, because I had the problem in the beginning too. More than one person has mentioned the Google Maps app as the culprit. Delete the app and try connecting, then restore the app. In my case, I updated everything on my phone, IOS and ALL Apps. Then totally cleared my cars system of ALL phones and reset it to factory. I actually did the factory reset on the car multiple times to make sure everything was reset. I know it shouldn't be this hard, but I finally got it to work.
