The activated online function of HERE thing applies at the same time very well in combination with installed maps. Again increased accuracy I suppose at times, despite online function still faster than the competition, because the maps yes is already there.
HERE is in addition to the Amazon Maps app officially installed on the Amazon App Store, although the app from Amazon actually been used here-maps (it would have licensing issues may be similar). This off-line navigation is also available on the fire phone etc.. Specifically, this means that depending on the selected country for which you want to have off-line navigation, the entire card material can be downloaded and means several hundred MB per country, with Germany about 1 GB. For the fire phone absolutely no problem, works flawlessly.
