There may be something I'm missing about your map download, but that's what I can recall from memory.
I called Garmin this morning, they said I have to purchase City Navigator, but I have seen several threads where people were aboe to download it free after purchase, had CD sent to them, and then those who had to pay, so not sure.
I will register the unit with Garmin today and see what they offer. What is IIRC?
