But with Lumia 640 you cannot save offline maps to SD card! That is just ridiculous. Unbelievable.
I believe there are still ways to save them to the SD card, search the site. That being said, maps and navigation really don't use much data at all anyways. I don't understand why people somehow think otherwise. I remember I checked my data usage on a 40 mile trip a couple years ago using Google maps and I think it only used like 3 mb of data or something really low like that.

Google Maps users actually report that it uses surprisingly little data, about 1MB per 10 miles of travel, which gives you a great excuse to take a road trip (without the guilt trip)."
