Thank you for the information. I will try this later this week and keep you
informed. BTW, i can remember some years ago when i have not used OSM Data on
may Garmin but on a smartfone navigation system with OSM, there was the same
fault on that device with a long detour. But after some data updates the
routing failure on that device was goneVon meinem Samsung Gerät gesendet.

Betreff: Re: [mkgmap-dev] crude routing of my gpsmap 276Cx
Hi Manfred,I don't know the actual signs and I don't care if the tagging is
right or wrong. At least the combination of bicycle=yes and foot=no on
https://www.openstreetmap.org/way/25285589 looks very
wrong:bicycle=yesfixme=check access
rulesfoot=nohighway=tertiarymaxspeed=30maxweight=7.5name=Brandenberger
Straßeref=K 30Anyway, it seems that mkgmap sets the correct flags for the road,
the Garmin algo seems to simply ignore the "no-through-route" flag when the
detour istoo long. I've tried this with a sample file where the shortest route
goes through a road with access=destination + highway=residential and the
longer routejust has ways with highway=residential. As long as the detour is
rather small Mapsource takes the longer (allowed) route when using the car
profile.All other profiles seem to always use the shorter route. So, either
something is wrong in the map data (problem in mkgmap) or something is wrong in
the Garmin algo.Please try if you can reproduce the long route using a map
created with mkgmap r4292 and the default style coming with that
version.Gerd________________________________________Von: mkgmap-dev

routing of my gpsmap 276CxFor your additional information, i think the tag
access=destination is to be seen with the additional tag for weight limit, as
the street is not allowed to be used for cars heavier than 7.5 tonsVon meinem

[email protected]: Re: [mkgmap-dev] crude routing of my gpsmap 276CxHi
Manfred,I tried to reproduce your results with BC but I get a different
route.at the moment I wonder why Mapsource shows the shorter route when using
car/motorcycle. The wayshttps://www.openstreetmap.org/way/25285586 and
https://www.openstreetmap.org/way/25285589both have the tag access=destination,
so my understanding is that cars should not be routed through them, but this
seems to be ignored. I'll have to find out
why.Gerd________________________________________Von: DD8KQ

276CxHi Gerdit's really weird. Trying this with MapSource you are right, there
is nolong detour. But, then, i tried the same with BaseCamp and you knowwhat,
BaseCamp produced on my Laptop this detour, see attached pictureTest2.And just
for testing, i tried the same area on a Smartfone running theNavigator App with
OSM maps, and this progromm is routing the samedetour, see picture
screenshot.So for me there must be something in the OSM Source regarding the
streetK30 which will cause the strange routing. But my experience is too
smallto figure it outAm 25.09.2019 um 11:12 schrieb Gerd Petermann:> Hi
