https://www.openstreetmap.org/way/27866666/history#map=15/40.4752/-3.9411 Trying to route along this route crashes the GPS device - not sure what i going on here. In demo mode - just set location to: https://www.openstreetmap.org/way/27866666/history#map=18/40.48063/-3.94040 and route to: https://www.openstreetmap.org/way/27866666/history#map=19/40.46711/-3.94385 (Calle Castillo de Ponferrada) The route will first be normal pink, however as soon as it goes onto the Calle Castillo de Alarcón it will keep on routing - but the pink colour is gone. Then after maybe half of the road it stops routing and asks to recalculate (which will be in a loop if you click yes). map produced with. start /low /b /wait java -jar -XX:+AggressiveHeap -XX:StringTableSize=1000003 -Xms15000M -Xmx29000M C:\openmtbmap\mkgmap.jar --max-jobs=8 --order-by-decreasing-area --code-page=1252 --add-boundary-nodes-at-admin-boundaries --nsis --index --levels="0:24, 1:23, 2:22, 3:21, 4:20, 5:19, 6:18" --overview-levels="7:17, 8:16, 9:15, 10:14, 11:13, 12:12" --add-pois-to-areas --pois-to-areas-placement=entrance=main;entrance=yes;building=entrance;barrier=entrance --reduce-point-density=3.4 --reduce-point-density-polygon=6 --add-boundary-nodes-at-admin-boundaries=2 --poi-excl-index=0x6405,0x4316,0x2f00 --cycle-map --check-roundabout-flares --ignore-fixme-values --housenumbers --road-name-config=C:\openmtbmap\openmtbmap_svn\roadNameConfig.txt --split-name-index --link-pois-to-ways --ignore-turn-restrictions --polygon-size-limits="24:16, 23:14, 22:12, 21:11, 20:10, 19:9, 18:8, 17:7, 16:6, 15:5, 14:4, 13:3, 12:2, 11:0, 10:0" --description=omtb_es --show-profiles=1 --location-autofill=bounds,is_in,nearest --route --country-abbr=es --country-name=spain --mapname=64130000 --family-id=6413 --product-id=1 --series-name=omtb_spain_26.06.2020 --family-name=mtb_es_26.06.2020 --tdbfile --overview-mapname=mapsetc --keep-going --area-name="spain_26.06.2020_omtb" D:\openmtbmap\maps\64130028.osm.pbf 1>NUL 2>NUL Routing setup on device as: ATV/Off Road Driving Minimize Distance No Avoidances but I think this does not matter. I have uploaded the broken tile/map here: https://openmtbmap.org/maps.7z the osm.pbf for that tile is: https://openmtbmap.org/64130028.osm.pbf I have no real clue what is happening here. If you set highway=residential from road_class=0 / road_speed=2 to say 1 / 1 crash is even earlier. I cannot find anything special looking at the road with GPSMapedit. Garmin Edge devices supposedly crash too - not sure about other devices. Felix
