Magellan has released each of the various Maestros (3100, 3140, 4040, 4050) with different software versions and different map screens, fonts, and features. Thankfully, Magellan has updated the 4040 to version 2 of Maestro's software, and it now displays the estimated arrival time and uses a larger font that's easier to read.

Users had reported buying Maestro 4040's with the 2.24 firmware already installed, but until this week the update hasn't been available for download for existing Maestro users.

Unfortunately, there's still no update for the Maestro 3100.

The Maestro 4040 firmware update is available via Magellan's support site.
