nuvi 200 question

Hello i had a question about the nuvi 200.

I''m a motordriver and like to drive routes which i downloaded on the
internet. I got myself a nuvi 200 and discovered that this navigation system
can''t read the routes when i download them from internet. Now is my
question if there is some software available so my nuvi 200 can understand
the routes and i can upload them to my navigation system and drive these
routes???

Thnx

A newbie
