Garmin nuvi 1440

 

hello guys!
i recently bought a garmin nuvi series 1440 and i was wondering if it's possible to load the routes for trucks. I tried to find smth on the internet but with no success ...i was thinking that maybe it could be possible to (i don't know..) replace the sw of the said model with another one of the nuvi series that naturally comes with trucking routes when sold. Has anyone ever done that?
Thanks for u help... smile
