I understand that. I'm not asking for reverse engineering, only for a way to write a style rule that appends the maxspeed tag value to the output string that ends up being the name Garmin shows on the unit.
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. On Thu, Jul 21, 2016 at 8:02 PM, Warin <61sundow...@gmail.com> wrote: > Dave, > Garmins mapping has evolved over time.
