I have the Garmin nuvi 1390 with the Europe nt 2011 on it, then I have SD card with Adria 3.0 map on, my issue is when i try to find any town or adresses from the SD card (witch i know exist) it can't find them, but when i use the map picture screen and go to the location from any adress located on the Adria map it can find and calculate it and ready to drive, what can be wrong?
The SD card is formated with FAT 32, and Adria is on like GMAPSUPP.IMG,
Seems that on the Garmin unit I can't find any file of the size of Europe NT 2011.
Hiden files or somehow crypted?

File structure of new Garmin Nüvi models (12xx, 13xx, 14xx) is different from the previous ones.
Supplementary maps have to be added to \Map directory in these models, not to \Garmin directory. As this directory does not exist, it should be created either on the internal flash disk or added SD card. The supplementary maps can be givenas any name ending with .img. That means that if you have four different supplementary maps, you can name them as Europe2010.img, Australia.img, USA2009.img, BritainTopo.img, so forth. This gives you the opportunity to load more than one supplementary map to your internal or SD card.

Sorry, it does not work even if i do that- :smilie_h_001:

check in tools/settings/ about/content can you select another map set , or in tools/manage my data/map sets check there can you include new map set, and check there does device see you adria route 3.0 map set!
