The top 5 best mobile navigation systems with offline capability
(All About Windows Phone)

Car site Auto Evolution has put up a useful list of mobile navigation applications (i.e. for your smartphone, as well as, in some cases, your car) that have `offline maps` capability. As featured for years in Nokia Maps, which then evolved into HERE Maps and then forked (ahem) into Windows 10 Maps. But you know the deal - lose cell coverage and your mapping app on your phone is still able to navigate you to a destination. Perhaps with no traffic awareness, perhaps with less POI, but it all does still work. There are a variety of free and paid applications and services, and the article summarises them well.
