Sorry for hijack, I was looking at this unit because I need to buy a new GPS, one that works for kayaking and also for the bike. My question is, are these units delivered with the Mapsource software, and everything else needed for creating routes/tracks? I understand that the advantages over the nuvi 550 are numerous, including the fact that the BlueChart. Are there any disadvatages?

Lastly, could someone explain what is the difference between this and the zumo 550/660?


Edit: I think I answered most of my questions with the 478 thread :)
