We needed a phone/data compatible iPad to get the needed GPS built in. We've used the free data a few times. Tomorrow we cross into Canada on our boat and are trying to get Canada data access set up. For a tiny amount of $$, supposedly we can get free-but-slow Canada data service on the iPad. I was on the phone with T-Mobile about two hours today. I'll not bore with details here. I'll let folks know how it works out.
