Working with Garmin maps I can say that there is no tag for height restrictions, only truck yes/no. I think you have discovered a feature of NT maps, which only Garmin themselves can compile.
As ajoessen says, you can compile your own map and implement a rule that restricts trucks in the Garmin map if height > x metres.
Success, thnx to all that came with suggestions. The mapsettoolkit really worked. I started the program and saw that a long list of debris (old map entries) was there. Only needed to select and uninstall these and then, … after startup of mapsource, I saw that the osm routable map of the Netherlands was there again.
Thnx again, Hein
Thank you, ajoessen and Beddhist!
I think I’m not mature enough to start compiling myself but I hope to reach this within some months!
Indeed the “truck” features of my Dezl look like they are quite detailed: initially one enters truck height/width/weight… and the restrictions leading to a detour are then identified, criterion by criterion, before the complete traject is drawn; for instance for height I get a screen locating the “faulty” bridge and its height limitation, etc.
I thought this corresponded to some equivalent to a “maxheight =…” tag.
Thanks again for both the great work, and the efficient reactions here!

At the moment Mongolia is covered with two tiles.
63241379.img // MN-Ulaanbaatar // East
63241643.img // CN-Urumqi // West
I had downloaded them together with the Russian Federation. To my surpise the western tile appeared all blue (water) on the 60Cx.
To check I only downloaded those two tiles again and constructed an GMAPSUPP.IMG out of them. Same result.
Also renaming 63241643.img to GMAPSUPP.IMG will show the whole square as blue on a 60Cx.
Hope this will be ok at next update.
As some of you know I’m working on a new version of the website where it will be possible to provide multiple types of maps with worldwide coverage.
A first beta version is available at: [[removed for the time being, send me an email if you want to test]]
For now I’m settling on a generic routable and a routable bicycle map and hope to expand later with a nautical map as well. Please test it and tell me what you think. Ideas for improvements are very welcome, but don’t complain about the styling unless you have actual code to contribute: I suck at CSS and accept it.
What’s new and improved:
Known problems:
If you visit the page you might run into temporary bugs, I’m actively working on it.
Last request: Please don’t spread this URL to other forums etc. It is a very temporary URL and will break soon. I don’t want people end up confused and complaining about 404 errors later.
Except for the first one these points apply to the regular garmin.openstreetmap.nl site too.
Edit: you found point 1. already…
Thank you for your comments JaVaWa 
Thanks. I will update this.
Great, I don’t have a Mac so didn’t know this. Will update as well.
Cool, Leaflet seems much faster indeed. I’ll look into that.
Yes, but that one is about to get discarded…
I’m not so happy with this Lambertus,
Type file name (openfietsmap_lite.typ) is too long
Styles are the default styles, not my openfietsmap style.
Better test this first in private with a few people.
That’s right, the name of a typ file cannot be longer than 8 characters (excluding extension)
I’m pretty sure I’ve seen the typ file in action, so I’m not sure why you think it’s too long?
Edit: typ filename is now shortened.
I thought that this topic was private enough, but opinions vary apparently.
Well ok, I’ll remove the link and wait for your comments. In the mean time I’ll try to implement Leaflet, but time the coming days will be in short demand.
The typ file works in Mapsource but not on the GPS (8 characters max, like Javawa said).
More important is that you didnt use my openfietsmap style files, so this map is the same as the generic one except with the OFM typ file (which makes no sense).
Can you mail me your mkgmap settings?
I discovered the error, caused by copy/paste. I’ll run an update tomorrow. The Mkgmap settings are on their way.
I could help with that, if you want. I’m not saying I’m an expert on Leaflet, but I experimented a lot with it.
I saw you use a kml file to load the rectangles. Leaflet doesn’t have kml support built in (yet). One way to solve that is to use geoJSON; or use an external kml script (but I didn’t test that last one).
Thanks, I have sent you the up-to-date styles and typ file.
Thanks for your offer JaVaWa, I was already wondering if KML is supported.
I can change the script that outputs the KML to geoJSON and would appreciate it if you can have a look at the website. All the map code is in openfietsmap_lite.js. I’ve added some extra comments. In the mean time the website can continue ot use OpenLayers as it has been for years, that way I can focus on bringing this live and optimize later.
I hope my coding is not too incompatible with Leaflet…
Thanks Ligfietser
Forget to mention you might use one of the latest mkgmap versions, it has some improvements, like more languages in the installer (Dutch, German and Spanish) and it supports now gmapsupp’s > 2 Gb (Dont know if your regions are that big though).

Hi
When is the next a planned update from OSM?
The dataset seems to be from 01-APR-2012
I am keen to compile some new maps on my Garmin, after having made many edits (inserts) on OSM.
Cheers

That might be a good thing. If I understand correctly, on April 1 the database purge started to remove data from providers who didn’t accept the new licensing terms. Therefore, post 4/1/2012 data should be less complete.
