Well then maybe what you need to do is stop waiting and try a free alternative , developed in an open way and in which you can actively participate.
Your name: OpenMaps . A free application for iOS that allows us to access OpenStreet Maps from a native application and with perfect operation, plus great options such as: iPad and iPhone adapted application, social features, map editing and real time corrections from your iPhone…
If we also pay 2.69 euros for the paid version we can access the offline function by which we can download maps and access them from anywhere , even if we do not have Internet, and also the step-by-step navigation function for the car.
We must remember that one of the bases that Apple uses for its maps, besides TomTom, is OpenStreet maps so we are not talking about a second-rate product, although it is true that the maps are not at all pleasant to look at.
