Looking around the internet I see several people say they don't use the built-in maps on the explorer+ for navigation for hiking, and they prefer some other maps on their smartphone. I am trying to decide whether to get the mini or explorer+, and the main reason I see to get the explorer+ is for the built in maps. But if these maps aren't very good for hiking navigation, then it seems I'd be better off getting a mini. So far I have no experience with either the mini or the explorer+, and welcome any insight that others might have about the maps on the explorer+. Correct me if I'm wrong, but I assume that any maps I could download and use on the mini (through the earthmate app) could also be accessed by the explorer+ through earthmate. Thanks.
