[mkgmap-dev] problem seeing OSM maps on nuvi 255w

Hi,

I'm generating maps for Ontario and Quebec here in Canada and I'm
having a problem seeing the OSM maps on my Nuvi 255w. I can see the
OSM map name in Tools -> Settings -> Maps -> Map Info but when I
enable the OSM map and disable the built in North American map, I
still can't see the OSM maps.

Here are the commands I'm using to generate the maps:

java -Xmx2000m -jar mkgmap.jar --tdb --latin1 \
  --region-name=Ontario --region-abbr=ON --country-name=Canada
--country-abbr=CAN \
  --series-name="OSM Ontario" --add-pois-to-areas
--ignore-unnamed-areas --road-name-pois \
  --route --remove-short-arcs --drive-on-right --check-roundabouts
--family-id=3425 \
  --family-name="Open Street Map Canada $FAMILY_DATE" --product-id=1
-c template.args

java -Xmx2000m -jar --tdb --latin1 \
  --region-name="Quebec" --region-abbr="QC" --country-name="Canada"
--country-abbr="CAN" \
  --series-name="OSM Quebec" --add-pois-to-areas
--ignore-unnamed-areas --road-name-pois \
  --route --remove-short-arcs --drive-on-right --check-roundabouts \
  --family-name="Open Street Map Canada $FAMILY_DATE" --family-id=3426
--product-id=1 -c template.args

java -Xmx2000m -jar mkgmap.jar --tdb --gmapsupp --latin1 \
  --country-name=Canada --country-abbr=CAN --add-pois-to-areas
--ignore-unnamed-areas \
  --road-name-pois --drive-on-right --check-roundabouts --route \
  --family-name="Open Street Map Canada $FAMILY_DATE"
--description="Ontario and Quebec, Canada" \
  --remove-short-arcs ontario/*.img quebec/*.img

I added '--draw-priority=30' to all three commands and the resulting
map is visible but the roads appear behind the roads from the Garmin
North American maps even though they are turned off. I *could* just
plug the GPS unit into my computer and delete the Garmin basemaps and
North American maps but I thought I'd ask here first before I do that.

So, does anybody know what could be wrong? My Nuvi 255w has software
version 5.70 and GPS SW Version 3.70b.

Thanks, Ben
