I have AUDI A6 2001 made with Navigation Plus RNS D. I am journalist and it happened to come to Greece now. I find no update for Tele Atlas CD map 2006 made. Tele Atlas as far as I understand is not going to make update for commercial reason. Is there any possibility to convert existing for example Navteq, Tele Atlas or Epsilon maps of Greece to be used in Navigation Plus. I have already bought these maps but use them on smart phone. I think it is not safe to use 2 screens in the car.Thank you.
