I was hoping to use the built in weblink for Here maps, as I have used them offline with success in out of the way places, but that was with the old Nokia and then windows phone where it was built in.
I'm now having to retire windows phone and assumed android would give more choice but found this one for carplay

I like the idea of the android head units with built in everything but too many issues
