Iran map for GPS devices is one of the most important problems for GPS users in Iran. I bought a GPS from a company about 9 months ago, they gave me Tehran map too, but after my first check to send and receive data to my GPS device, I removed the GPS map !!!
then I called the company but they told me I should pay for the map again.
I did not pay for the map , because on that time I was thinking about GPS map. Now I am happy to tell, my first GPS map is ready to use for others !
