MP (Polish format, cGPSmapper)
Open BetaMP (Polish format) is an open plain-text source format for mapmakers, created for the cGPSmapper compiler. It is not a ready-made map: an .mp file does not load into a navigator. You build the map from it — NM2 for older Navitel units via GPSMapEdit, or .img for Garmin via cgpsmapper.

About MP Format
MP, also known as the Polish format, is a plain-text source format invented for the cGPSmapper map compiler. Inside is ordinary text: [POLYLINE], [POLYGON] and [POI] sections, each object carrying a type, a name and a coordinate list per detail level. The file opens in any editor, reads by eye and is edited by hand — that is what the whole amateur mapmaking scene rests on.
Understand this up front: an .mp is not a map for a navigator. No device and no navigation app reads it directly. It is the INPUT to a build: from an .mp you compile the format your device actually understands. There are two chains. First — GPSMapEdit: open the .mp and run Export to Navitel NM2; NM2 is understood by older Navitel Navigator releases, roughly up to 9.1x. Second — the cgpsmapper compiler: it turns the .mp into an .img for Garmin devices.
What we actually deliver. The export writes the geometry of the selected layers, object labels, Polish format types and detail levels — that is, a basic, NON-routable map. The routing graph sections (RouteParam on lines and Nod nodes) are not in the file: they are built at the next step by cgpsmapper and GPSMapEdit themselves. We say this plainly rather than in fine print — if you need a map that works out of the box, take Garmin IMG or OsmAnd OBF, which we compile in full.
We do not produce Navitel's native formats: NM2 is produced on your side, in GPSMapEdit, while NM3 and NM7 are closed and cannot be built by any third-party tool at all. So .mp is the honest maximum the service can offer for Navitel: detailed, fresh OpenStreetMap data in the shape a map is assembled from by hand.
What Program Opens MP Files
The following programs and applications can open, edit, and work with MP (Polish format, cGPSmapper) (.mp) files exported from OSM2CDR:
Who Uses MP Maps
How to Export MP
How to Open After Export
- GPSMapEdit (a free map editor) — File → Open, pick the .mp; the map appears on screen and objects can be edited. Then File → Export → Navitel NM2 and copy the result onto the device into the NavitelContent/Maps folder.
- cgpsmapper (the compiler) — the command "cgpsmapper map.mp" in a console builds an .img for Garmin; the result goes onto the device as gmapsupp.img or is installed via MapInstall.
- Any text editor (Notepad++, VS Code) — inspect and adjust the content directly: object types, names, levels. The format is human-readable, and editing it by hand is normal practice.
- MapTk and related utilities — batch processing of .mp files: merging, filtering by type, syntax checks before the build.
- Routing: if you need a graph, enable it at the build step — cgpsmapper and GPSMapEdit can generate RouteParam and Nod nodes. Our file has none, and without that step the map stays "for display": it draws, but it will not route.
