anyone else got this, i'm on a route from Istanbul to Munich

I know there are certain countries that if you are driving to or from the GPS doesn't work because Google Maps doesn't support them...

Yeah i think its not a bug in the game but an issue with Googlemaps. In NA for example Mexico and the Central American countries are always off the map.
A schoolmate of mine works for Google and I understand that they still have issues with harmonisation of data from different countries for their global reach products as standards vary. Im not sure if and when this will change for us though at some point soon so that we can see all routes...
