Modern day GPS devices are essentially miniature computers. Many have a compact version of Windows, called Windows CE, installed, and the GPS software runs over top of it. However, GPS manufacturers often lock out this extra functionality. There are different packages and ways to unlock your GPS, however because there are so many different brands, it isn’t always one-size-fits-all.
I Googled for information on unlocking the Magellan RoadMate 1424 (the GPS I have) but the only information I found was a couple of people who couldn’t do it. Not deterred, I set off and entered the unknown. Read on for my story (spoiler: it ends in success).
