Just bought one as my first sat nav and im well impressed with it

But ive just plugged it into my pc to get the updates etc and i planned my route using tomtom home, now ive watched the demo route to see that im happy with it and iam, so what do i do to save it so that it comes on the screen when i plug it into my car? or does it save automatically?

Dont want to get in the car to find out i need to re-do the route


cheers
