[mkgmap-dev] Minimum size for a "_link" to process "destination"

Thu Mar 10 22:08:01 GMT 2016

If I recall correctly, Garmins don't use the road name for links.
Instead they use the name of the first non-link road, i.e. where the
link leads to. So the first bit of the exit ramp stays as a link (road
type 0x08 or 0x09), and a short bit in the middle gets the destination
as a name, so the GPS will announce "take exit to Mytown". There may be
more to it, but that is how I think it works.
