JNX
Garmin Tile Format
JNX is used by Garmin devices for storing files to display satellite maps available through a BirdsEye subscription. JNX is the so-called tile format which means that a large raster image of the map is divided into smaller rectangular pieces for faster display by the navigator.
PGX
JPEG-2000 VM Format
This is an image file format that is stored without the use of compression algorithms. It is used in the JPEG 2000 standard. This format is capable of storing only one single component, so it is limited to displaying grayscale tones. If you combine multiple PGX files, then you can make a color image.
