Hi i have Igo Luna with pongo skin and newest maps installed on a china head unit (android 8). It works fine but route calculation is bad, It guides me on some strange roads ro destination.I dont have historical raffic activated. it has not always been so bad. Wich file UX or other is responsible for wich calculations are availible. Is it possible to change this. In luna there is as far as i know only one type maps availible so this cant be changed or ?. Have searced forum without succes. If there is anything on forum i am sorry for asking.
