As for the gmap3d.img files for those maps... do they also work from the SD:\Map folder, or do they go into the SD:\Garmin folder? If more than one map has a gmap3d.img file, can I rename those too?
On my nüvi 1490 I can only get the gmap3d.img file to work from the SD:\Garmin folder, not the SD:\Map folder, hence the question.
