Add maxspeed to highways

Hi,

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 have these lines in my lines style currently:

highway=trunk {name ‘${ref|highway-symbol:hbox} ${name}’ | ‘${ref|highway-symbol:hbox}’ | ‘${name}’; addlabel ‘${ref} (${name})’ }
highway=primary {name ‘${ref|highway-symbol:box} ${name}’ | ‘${ref|highway-symbol:box}’ | ‘${name}’; addlabel ‘${ref} (${name})’ }
highway=secondary | highway=tertiary {name ‘${ref|highway-symbol:oval} ${name}’ | ‘${ref|highway-symbol:oval}’ | ‘${name}’; addlabel ‘${ref} (${name})’ }
highway=* {name ‘${name}’ | ‘${ref}’ }

Rather then trying to reinvent the wheel, I’m hoping somebody out there has done this already.

Thanks,
Dave
