Hm, i will check out which should be the correct tagging of a road which are 
forbidden i.e for lorries of a specific weight and for all other cars this road 
is allowed. Regarding this specific street i have made a number of tests, 
moving the destination point on my garmin further down the road. And during 
these tests i found some points, where the garmin refuses to use the short way 
and proposes a longer detour. Might be, that the device only check 
access=destination without the other rules ?Von meinem Samsung Gerät gesendet.

Hi Manfred,Just to make that clear:I think that the long route is correct given 
the tags of the mentioned ways if the vehicle is a car. So, your first goal 
should be to correct the 
tagging.Gerd________________________________________Von: mkgmap-dev

routing of my gpsmap 276CxThank 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

[email protected]: Re: [mkgmap-dev] crude routing of my gpsmap 276CxHi 
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
