I frequently drive long distances in central Europe. Here Maps in offline mode works good enough for this but one thing is very annoying when I plan my routes: the big countries (Germany, France, UK, Italy, Spain) are divided into regions and every time I have to figure out which regions I will drive through so I can download the correct maps. Is there a way to make my phone, based on the suggested route, select the minimal amount of maps that is needed and download them automatically?
Well the only way you can use the offline feature of the here maps is by manually selecting and downloading the regions through which you will be travelling.
But i have the perfect solution for your problem why not use HERE DRIVE it has the capability of downloading the minimal map data so that you can travel through different regions without having to download the entire map , it has turn by turn voice navigation too.
EDIT:check the comments !
Hope this helped !
