 ### osd_map2d_ref_line_heading
 
-Draws a dashed line on the center of the map display, if using "up is north" setting. The line is aligned at the heading set by this parameter. This should be set to the same heading as an easily recognizable feature nearby the place you are flying, for example the same heading as the runway (if flying from a club), street or a nearby fence. So now you are able to compare the craft's position on the OSD map with this reference, making it easier to orientate yourself, better align directional antennas and so on. Default setting of -1 disables this line.
+OSD 2D Map reference line heading (0 is north, 90 east, 180 south and so on, -1 disabled). Requires using "up is north" map setting. The dashed line will be aligned to the heading set by this parameter. So should be set to the same heading as an easily recognizable and static feature nearby the place you are flying, for example a runway, a street, a fence, etc. Then you are able to compare the craft's position on the OSD map with this reference, making it easier to orientate yourself, align directional antennas and so on.
