Reading Third party Maps

I have a basic question:


How is Basecamp able to read and render a third party map installed in an SD card (or an internal memory of the device) without it being installed on the computer (Mac)? Does it then mean; all it needs is only IMG and unlock code? When I connect a device via USB to the computer (Mac) and open Basecamp, I can browse the map installed on the device.

So every time, if I cannot install a third party map on the computer, all I then need to do is create a Garmin folder in a USB drive copy the valid IMG and UNL file, connect the drive to the computer and open Basecamp to enable me to browse the map?

    Sorry but you're confusing me. We've discussed how you get the maps to be seen in Basecamp, you then mention mac and Mapsource, Mapsource is a Windows program. In any case I thought you wanted to move your map from the card to your nuvi so it worked from the internal memory of your nuvi?

    Moving a working map from a card to the Map folder of your nuvi will work, assuming you move as well any other necessary files.

    I was trying the other approach only because a basic copy into the device internal memory was not working. Hence I was trying instal the map in mapsource/basecamp. This way once I install the map in the computer, I can then further instal the map into the device via basecamp/mapinstall.

    I will try reset the device once again and try to copy.

    I tried to use the SD card. I think the map has an issue. Simply because I cannot see all the tiles cleanly. Some of them seem to miss. Will go back to map provider to check. I also tried to check the content of the image via gmaptool. I see that there is a sequencing error.

    I figured out the problem. The device does not support two versions of the same map. I deleted an earlier version installed in the device. And then when I put the SD card containing the new version, it works problem.
    But I still cannot copy the map image into device memory from SD card. It basically says it cannot unlock the map. I copied both the map and the unlock code into the Map folder in the device.

    But still I some how can read the new map version in the device (through SD card). Are the unlock codes tied to the SD card and hence cannot work when copied to a different location (device memory in this case)?

    It depends on the map and how it was acquired. Some maps are locked to a card, some aren't ... you really need to ask the map provider as I'm not familiar with the map you're talking about.

    The provider mentioned the license is locked to the SD card. I think that may be the reason, I am not able to either movie to the device memory or even compile it for Basecamp.
