Before you attempt this step you should have completed the directions in the prior post to download the latest firmware for your unit off the Magellan web site.

When you completed the final step in obtaining the firmware upgrade (shown above) it was saved to your PC hard drive…. you remembered where…. didn’t you?

My Firefox download manager is set up to save downloads to the desktop where I can see them easily.

After it completes the download, you should have the file… here is the icon on my workspace/desktop.

You may want to create a directory to put the extracted files, so create it first, but since there are only two files, if you want to extract them directly to the desktop it isn’t a big deal. You can just delete the later, or save them to another place, but I doubt if you would ever need them again.

It is a self extracting .Zip file, so if you “double click” on the icon, it should begin the extraction process.

Once it unzips it will start the install process.
