I’ve downloaded Gribeco’s Japan map from http://admincabal.com/osm/ and installed it on my Oregon 450. Unfortunately, the maps show no labels at all. I also tried to generate my own map, but the text is completely missing on my map, too. Oregon is running software version 6.10
I had the same (?) problem on my Dakota 20, while QLandkarte GT showed everything as expected (to be more specific: even selecting an element on my Garmin showed Lon/Lat values instead of their names). Dropping the mkgmap option “–ignore-osm-bounds” does the trick to me. So if you’re using this option, this might help.
Basically, I don’t have no text at all. I exchanged the font files(?) as described in Mkgmap/i18n and downloaded a japan.gtt to see if it could display Japanese characters at all (which it did). So displaying those characters in general seems to work.
But I don’t have a single string on the whole map, nothing is labeled. No cities, no roads, no POIs, nothing.
Do you have more information about that bug? Can I overcome the issue by using a TYP file that would avoid this bug?
I had the same problem on a “Western” Oregon 600.
I was able to confirm that the fonts I had installed did contain Japanese characters by
decoding the font data files (xor 0x76) and viewing them with a font viewer
installing a Japanese.gtt text translation file
The problem seemed to have been that my device can “only” display UTF8 but the map from admincabal uses SJIS. After downloading a UTF8-coded map from http://gpsmap.php.xdomain.jp/ everything works fine.
