Ok, I retried with V1340 and use the same options like Felix i.e. --index and --location-autofill=1, now I can search in MS.
I've send Felix' openmtbmap to the Nuvi 250, but this device is still asking for a State/Provinz and no search is possible. Maybe this is GPS related. I use a Nuvi200W Or else there is something missing in our OSM data that the rest have? Which country are you using? Is there any address data in the OSM data? I wish I could test my maps on another GPS to confirm. Or test someone elses map on my GPS. I have downloaded openmtbmap.org Berlin map and will try it tonight. Don't know if it was created with --index though. "Felix' openmtbmap"? Is that from openmtbmap.org? Which map? was it created with --index and did address search work on his GPS? In the mean time I try lots of different option combinations. Maybe I get lucky- I will inform you if it happens and I can determine what made it happen. BennieD
