A friend of mine has a Garmin nuvi 250 and asked me if I could help
upload custom data (actually ATV trails) to the GPS. I believe
additional data can be loaded using SD cards, but I have not seen the
unit and have not looked at the manual myself.
I was wondering if anyone on this list knows the format in which the
data has to be packaged, or knows of a piece of software that can
convert common formats to the format expected by the Garmin nuvi.
Daniel,
You might browse <http://reidster.net/garmin/>. I think those directions
are overkill for you, but parts may be useful.
Note that this will _not_ get you routes or tracks that you can tell the
unit to help you follow. It will just get you a custom base map.
Good luck,
Reid
