Getting favorites and other user data out of Magellan Maestro 4040

I bought a Maestro 4040 at Costco a few weeks ago and have been very
happy with it until now.

I used it on a road trip and marked some hard to find locations for
genealogy purposes. I saved the locations as 'favorites' but did not
write down the coordinates when I was there.

Now I'm trying to figure out how to get these locations (latitude and
longitude) into a database, preferably some standard format that I can
use with mapping software. I want to get it into a format that does
NOT depend on Magellan.

I called tech support for Magellan and they told me there is no way to
download any data from this GPS to a computer.

Any help would be greatly appreciated here.
