For years now I have been keeping all buildings as a separate transparent gmapsup /img giving it a higher priority/draworder then my normal maps - It has speeded up my daily runs without loss of detail - same could be done for rivers/streams etc. As a bonus I can ,if I wanted to, switch off/on buildings on my device, bit like contours. I update my buildings.img when necessary.
This is not an answer to the initial problem but it works

Nick Thanks Nick for the hint. I had already tried this approach to separate my topo map into three layers: base map, topo specific elements and contour lines but I get very different behavior on different Garmin models. Up to now I have done only a simple test with the commands and results shown below: #Base map: java -Xmx600m -ea -jar mkgmap.jar --bounds=bounds.zip --route --latin1 --code-page=1252 --country-name=ESPAÑA --country-abbr=ESP --family-name="OpenStreetMap Extremadura" --family-id=113 --product-id=1 --description="OpenStreetMap-Extremadura" --series-name="OSM-Extremadura" --area-name=España --overview-mapname=ESP-113 --mapname=55113001 --index --process-destination --process-exits --housenumbers --add-pois-to-areas --adjust-turn-headings --report-similar-arcs --link-pois-to-ways --location-autofill=is_in --drive-on=right --style-file=../resources/styles --style=base typ/ESP-113.TYP extremadura.o5m
#Topo layer java -Xmx600m -ea -jar mkgmap.jar --family-id=513 --product-id=1 --family-name="Topo Extremadura" --series-name="Topo-Extremadura" --area-name=España --overview-mapname=ESP-513 --overview-mapnumber=55513000 --transparent --draw-priority=26 --latin1 --code-page=1252 --style-file=../resources/styles --style=topo extremadura.o5m #Merge all layers (contours are prebuilt transparent 60213*.img files with draw-priority=28) java -ea -jar mkgmap.jar --latin1 --code-page=1252 --description="OSM+Topo-Extremadura" --country-name=ESPAÑA --country-abbr=ESP --family-name="OSM+Topo Extremadura" --family-id=313 --product-id=1 --series-name="OSM+Topo Extremadura" --area-name="España" --overview-mapname=ESP-313 --overview-mapnumber=65313000 --index --show-profiles=1 ../mapas/extremadura/55113*.img ../mapas/extremadura/6324*.img ../mapas/extremadura/60213*.img ../mapas/extremadura/ESP-313.TYP Legend HCx: each single tile must be enabled/disabled separately. Tiles of each layer are identified as OpenStreetMap-Extremadura (base map), OpenStreetMap (topo) and Curvas de nivel (contour lines). etrex 20x: only two maps are shown in map info: OpenStreetMap (base map) and OSM+Topo Extremadura (all layers). If only base map is enabled, background is black. Edge 800: map info shows three maps, but they all have the same name and properties and it's necessary to enable/disable them by turns to know which is which. As I've said, it was only one test and I probably have to play with description parameters to get a more homogeneous behavior, so any hint would be much appreciated.
