About Garmin JNX
Map of Congo-Brazzaville in Garmin JNX — an export of real OpenStreetMap data for the selected area.
JNX is a binary raster-tile container Garmin created for its BirdsEye satellite imagery service, supported on Oregon, GPSMAP, Montana and etrex handhelds. On osm2cdr the JNX is generated natively by our own Python writer: we render the chosen area into JPEG tiles via QGIS and pack them into a .jnx with a header, tile index and Garmin-format coordinates (int32). The file is marked device_id = 0 (all devices) and written with no DRM or expiry, unlike subscription BirdsEye files. To be honest: this is a single-zoom raster overlay — no routing or search, just a picture of your OSM map on top of the base map. The limit is 50,000 tiles per file.
Which layers are in the file
This file for the selected area contains:
- Roads
- Water
- Greenery
Coordinate systems
WGS 84 (EPSG:4326), selectable in the wizard
Units
Meters (projected in the chosen coordinate system)

How to use Garmin JNX for Congo-Brazzaville
- A Garmin device — copy the file to the microSD or to internal memory, into the Garmin/BirdsEye/ folder; after a restart, enable the layer in the map settings.
- Check before you set off — open the maps menu on the device and make sure the layer is visible: some models show raster layers only at certain zoom levels.
- Garmin BaseCamp — will show the map on your computer if the device or its memory card is connected.

FAQ: Garmin JNX for Congo-Brazzaville
Do I need a BirdsEye subscription?
No. We generate the JNX natively from your OSM map; the file is marked device_id = 0 and carries no DRM or expiry — it works without a subscription.
Can I navigate (route) on this map?
No. JNX is a raster overlay (a picture) on top of the device base map. Routing and search come from a vector map, not from JNX.
How many tiles fit in one file?
Up to 50,000 tiles. Beyond that the tile list is truncated; split large regions into several .jnx files.
Where do I copy the file on the device?
To the microSD card under Garmin/BirdsEye/. After a reboot, enable the layer in the map setup menu.
How is JNX different from Custom Maps KMZ?
Both give a raster layer over the base map, but JNX is a binary BirdsEye container with a 50,000 tile limit, while Custom Maps KMZ is a ZIP with KML and no more than a hundred overlays. JNX handles a substantially larger area, while KMZ is supported by a wider range of models.
