Place the JNX files in folder: Garmin/BirdsEye/ If the folder does not exist than create it
Coz JNX files are used in Garmin devices to show the raster maps available via BirdsEye service subscription. In the devices, these files reside in Garmin\BirdsEye folder on the internal disk or in the memory card.
The firmware patcher removes the limitation on number of displayed demo-maps.
NOTE:
Please note that the firmwares released after March 2011 are not compatible with the JNX maps made in MAPC2MAPC before version 444 or MOBAT2JNX version 1007, will most likely cause the device hang on boot. To make these maps compatible with latest firmware versions use the JNX fixer tool.

Anyway when you send a file without a subscription, you get that message, but you can still view a small part of the file as a sample. IIRC, an area of about 1 mile x 1 mile at the center of the image will be viewable on the GPS, it looks your sw isnt patched correctly or you have a corrupt JNX file.

No! Only recent models of Garmin hand held gps. Search and search here in this topic/forum and in the Garmin's site...
