Navigational guidance frightening (subjective opinion)

I have been the owner of a Kia Carens Spirit 1.7 CRDI for some time now. I was told when I was picked up that the latest Here card material was played up. I commute a lot between Frankeich and Germany (about Belgium). I noticed that the route is more than modest – an improvement (allegedly the Navi is learningable) on the route I favored (toll route) I can’t see. My smartphone (also Here app) shows a significantly better ro course. Sure, if I don’t know myself, on unknown routes, I don’t care about the way there – the main thing I get – but if I see that he offers me routes that need more time, then I find that uncool… For the settings – yes, I think I have seen the structure well and that all parameters are correct. What are your experiences? Greetings Inti31
