Upload Instructions:
Instructions for uploading the new software to your GPS18x USB using
Microsoft Windows 2000 or later:
1. Download the appropriate self-extracting archive file onto your
hard drive.
2. Unzip the files in the archive by running the downloaded
executable file. It is recommended that you unzip the files to
the default location of C:\Garmin, but you can browse for a
different location.
3. Connect your unit to a free USB port on your PC.
4. In the unzipped folder (C:\Garmin by default), select and drag
"081101000XXX.rgn" to the Updater.exe file. This will automatically
open Updater application. Note: XXX in the file name denotes the
software version.
5. Select "USB Device" button, then "GPS 18x USB..." from the drop
down list. Click OK. After a brief wait, the update will be complete.
