G'day arnon, welcome to GPSPower [New Yorkers are corkers].
You mean the last sentance in this post by Caty?:
If so, it means you can simply drag & drop the firmware file onto the WebUpdater icon on your desktop, or if you like, you can drag it onto WebUpdater.exe in C:\Garmin\WebUpdater\Program Files [or Program Files (x86) if you have 64 bit OS]. You must first have the device connected in MSM and change the XML file as said above and don't disconnect before flashing via WU. The file will be transferred to the unit's .System folder as GUPDATE.GCD and the unit will then downgrade the fw on the next reboot.Originally Posted by catymag
