Hi folks, hoping someone can help. I today picked up my car and after leaving the dealership i bought it from realised that there is no SD card for the navigation for maps. I fully intend to speak with the dealer tomorrow once open, but i have the feeling they will encourage me to part ways with more money than i'd like. What are my options here? Can i download maps onto an SD card and install them myself? I have added a pic of the unit but dont know the model number etc.
