[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
