1450LMT and map segments from MapSource

I just upgraded from a Quest to a Nuvi 1450LMT and I'm a bit confused about the need to download maps from MapSource. I have the latest maps (2012.30) installed on BOTH the 1450 and in MapSource. My understanding is that the 1450, therefore, already has all available map detail for the entire US and Canada installed. Why would it be necessary to send any MAPS from MapSource to the Nuvi?

To ask another way, if I plan a route in Mapsource and send waypoints and routes from MapSource to the Nuvi, do I also need to send maps, too??

    No, you already have full maps of North America. Just send your routes and waypoints and you're good to go.
