First off I'd like to thank everyone who has been working on this, it's
a great addition for anyone using OSM on a Garmin device.

I had a go at producing a routable map for my local area but whenever I
transfer it to my eTrex Vista HCX it always routes on the in-built
basemap no matter what I try. 

I built the maps with the following commands[0]:

      * wget -O meonvalley-20081207.osm
        "http://www.openstreetmap.org/api/0.5/map?bbox=-1.2514,50.8892,-1.0928,50.9916"
      * perl osm2mp.pl meonvalley-20081207.osm > meonvalley-20081207.mp
      * java -Xmx512M -jar mkgmap-route-779/mkgmap.jar --route
        meonvalley-20081207.mp

The image is then transferred to the Garmin via USB mass storage.

If anyone who has successfully built a routable map can shed any light
on what I'm doing wrong I would be most grateful. 

Cheers,

Andy
