Hi, im using an android headunit with igo primo and google maps. But google maps is very slow, so mainly igo primo. Also im rethinking of using just a smartphone for navigation, because everytime i get a new (second hand) car, i need to buy an expensive headunit for it. So thus i am now thinking of going to an android smartphone with igo primo. Only thing is that i have to seach a solution for a backup camera, because i have no clue yet if that is possible on a phone. So in short, a dedicated device for now.
