One of the features of the Oregon etc series is that you can disable maps ; great, I tend to have a separate settlement and contour map with my osm import and disable them when necessary.
Trouble is knowing which map you are disabling as they all have the same descriptions ; I tried various options with mkgmap (–description etc) but that didn’t work;I then discovered that the descriptions are found in the IMG header of each file located at at 0 x 49 ; changing the text at this offset worked but the Oregon now displays ALL the altered descriptions on each map listed in the dis/enable section.
Is there a way of ensuring each map just shows its own description? I wonder how other Oregon etc users know which map to disable other than through trial & error?
