Well,

the default style rules in mkgmap evaluate maxspeed to calculate a so called 
road speed value which is used

by the Garmin routing algo.

But we don't know any way to store the value in the map so that it woud show up 
in the device when you

pass the node. I know that modern Garmin maps have this feature using so called 
NT maps, I don't know

any place in the older img format where this information could be stored, but 
maybe we just didn't find

it yet.

I posted this on the Garmin OSM forum but nobody responded. Maybe someone here 
can help with this.

I recently added maxspeed to many highways in my neighborhood and am looking 
for a way to have them display on my Garmin Montana. Mostly I would use this 
information while driving here and there to show me roads that don't have a 
maxspeed tag already. I'm looking for a style directive that will append 
maxspeed information to the highway-symbol and ref for the standard highway 
types.

I'm not currently aware of anything in the OSM to Garmin toolchain that is 
capable of encoding maxspeed as of yet.  As far as I'm aware, the only data 
consumer that is using lane or speed data is Osmand at this time.
