How to upgrade map on SD-Card of a car navigator?
Hope someone can help me. My thinking is, if I only upgrade the map, it should be easier to done, when I have success, I may in the next step thinking about how to upgrade the navigator device software, which may be difficult since I think I even not sure if I can connect the device to my computer.
By the way: How do I check how old my current map is?
Thanks a lot.
