Ah.
Not so much a tagging issue .. a 'style' issue.
Is there a gittyhub talk group?
You could take the data and loacly convert the ref value to include th
emax speed value ..
for your example
ref=Ak9
maxspeed=30 (mph .. stored in kmh so you will need a conversion for mph
to
ref=Ak9)(30 mph
mexspeed=30
...
That may then render the way you want it. Bit of a work around, would be
easier with direct coding.

Let me put it another way. It seems to me that if one can use a style
in such a way to display a road name from the name tag, plus a route
number from the ref tag, then it ought to be possible for me to create
a style that will show the value of the maxspeed tag. I mean, certain
of the style directives (like the ones in my snippet) only create
labels that are referenced later when styles are actually being
applied to objects during map creation. Instead of seeing "driving on
Ak 9 (Main Street)" on my Garmin screen I want to see "driving on
Main St (Ak 9)(30 mph)". It should be possible to make a style rule
to create that result. I'm just not clever enough to figure out how.

Dave,
Garmins mapping has evolved over time. It is not open source nor
do they release the commands etc that they use.
So things are reverse engineered to get Garmin maps from various
sources (including OSM).
While maxspeed may be important for some .. it may not be high on
the list of things to do for those doing the reverse engineering.
So in terms of getting it on your Garmin .. not now. But maybe in
the future.

Hi Dave,
"there's no known way to simply append that tag to a label or

no, I think that should be possible when the way has the maxspeed
tag.
I refered to a different feature which shows a road sign with the
maxspeed value
and also allows to warn the driver when he is faster.

Thanks for the responses.
I assumed because we can append ref tags to a highway name one
could just do the same for maxspeed. It's just another tag after
all. Obviously, there is a lot of interplay between mkgmap and
the Garmin internals that I don't understand.
Gerd, what you're saying is that there's no known way to simply
append that tag to a label or highway name. Correct?

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.
