Don. I think our iPad experience are opposite. Have had iPads a few years now and it is my go to, even more than my iPhone. Currently have the 11 inch Pro and pencil. Did try keyboard cover once. I’m not a good typist, just hunt and peck. My laptop sees much less use. There are times I use both.
I’ll have to look at the sharing map info. I do know iPhone links to CarPlay but never looked iPhone to iPad. I tend to favor Apple Maps over Google, although my built in maps in the Ridgeline maybe Garmin. I do have a Mobley in the truck for internet instead of iPhone hotspot.
