I have a Garmin 260w from the last two years, and I tried to update software using web updater. And through the web site of my products, I already registered the gps, and that apps said that I have the last version. My Garmin has 4.00 version and I saw another Garmin 260W with software version 6.40. How can I update my GPS, and how do I update the firmware? please help.
