I've installed TortoiseSVN which also contains options to create or apply a patch,

if you don't prefer to use the svn command line tool.

An: Development list for mkgmap
Betreff: [mkgmap-dev] Any way to get SPEED LIMITS to pop up on my Garmin GPS, like they do on City Navigator?I have been entering SPEED_LIMIT=X in the OSM maps and it would be nice to see this info on the maps I build. The NUVI DASHBOARD on my GPS pops up Speed LIMIT when running City Navigator 2016.20. Has this been implemented in mkgmap?
Greg
