Thread: About Garmin maps Additions files (gmap3d-JCV-gmaptz-ASR-G2S)

Would that be the X:\Map\JCV folder or would that be the X:\JCV folder? (X: being the drive designation for either the nüvi or the microSD)

Here is the subtle difference that I believe I now understand. The nuvi 1490 card map files are in a folder "map", and the JCV file goes in a folder called "garmin" as catymag said....I did not understand this and put the JCV subdirectory and the img file in the "map" folder and was not able to get JCV to work...Older nuvis, such as the 265WT, put the maps in the "garmin" directory on the card so the JCV directory for those nuvis would in "garmin", but the card on the 1490 appears to require both a "garmin" (for the JCV) and "map" directory. On the 1490, there are different versions of the same map (that uses JCV) both in main memory (.system\JCV) and card, so there are JCV subdirectories in both places....whew...
Thx Catymag
