The Magellan Maestro 4250 is a GPS navigation device that assists drivers when they are on unfamiliar roads or are searching for a route to avoid traffic jams. On occasion, Magellan releases software updates for their GPS devices. These updates can be downloaded from the Magellan website, then installed on your 4250. Previous updates have given users more control of which traffic reroutes to use, improved map panning and zooming and reduced search times for points of interest.

Step 1

Go to the Magellan website, and navigate to the "Support" tab. Click twice on "Manuals & Software Updates."

Step 2

Click "Software Updates," then "Vehicle Navigation." Click on "Maestro Series" and "Maestro 4250 North America." Click "Download" and save the update to your computer.

Step 3

Open the file when the download completes, and click "Next." Connect the 4250 to the computer with a USB cable, when instructed to do so.

Disconnect the 4250 from the computer when notified that the update is complete. Once disconnected, the device reboots in order to complete the update.


  • Do not disconnect the GPS while the update is being applied. This can damage the device.
