I have a 1.5-year-old nuvi 1450. The device came with lifetime maps...I know it's questionable whether lifetime maps are worthwhile for a built-out part of the world like the U.S./Canada, but on Black Friday all of the Garmins were pretty much the same price (read: cheap) so I took it.

Anyway, now I'm trying to apply updates since we're headed out to Phoenix this week and that is one part of the country where I can see a new road or two having been built since late 2011.

But...it won't let me update all of U.S./Canada due to space limitations!

Since, at a macro level, the size of a U.S./Canada roadmap shouldn't significantly change in that time (maybe by a percent or two max), I'm guessing this is because of how the data is stored in the unit? I unchecked the "backup" option, thinking maybe that was causing the device to retain two full sets of maps. Didn't work.

For now I'm updating the western maps. Good enough for the time being, but this summer we'll head back east and if we encounter a new road somewhere it'd be nice if our Garmin was aware of it.

I know I can acquire SD cards to add all sorts of maps to a Garmin, but it seems like internal memory of a U.S./Canada product in 2011 should be able to handle U.S./Canada maps in 2013. It's not like we've annexed all of Mexico or something...
