I have Apple CarPlay in my Cayman and I use Google Maps for the back roads because there is a way to save maps to the Google Maps program on your iPhone (under the top left menu, go to Offline Maps). I created about 12 offline maps of my city and surrounding areas. I need to upload a few more because I've neglected parts of the state above me. Then, out on the road, it accesses the needed map without downloading it, saving cell data connection time along with being present when I'm out of my carrier's area.
