46er: Actually I was addressing Nascar's question.... There is really no reason to get the DVD (not CD... the maps are much too big for that) unless you just don't like downloading.
I always like to have my own b/u copy of things if at all possible. I did the same with getting a copy of XP from Dell, as they did not include a copy. Old habit I guess.
I turned the NUVI on this morning and a message came up telling me about an update available for downloading. I don't ever recall seeing that, but I don't pay that much attention.
