The *.rmap type (Twonav format) is not in the list of the supported formats (currently supported by MOBAC). Please find enclosed a rmap example file. Regards, Jean-Marc
RMAP is a proprietary format invented by CompeGps / TwoNav, it is not officially documented and cannot be read by OkMap. The RMap format that OkMap reads is actually a Sqlite database similar to MBTiles. If you have the technical documentation to read it please let me know.
