Instructions for uploading new software to your GPSMAP® using Microsoft Windows 98 or later:
Download the appropriate self-extracting archive file onto your hard drive.
Unzip the files in the archive by running the downloaded executable file.
Connect your unit to a free serial port (Com 1, 2, 3, or 4) on your PC with a PC interface cable. Note: Not all Garmin products have PC interface cable accessories. For many fixed-mount marine applications, the user will need to build an appropriate cable to accomplish this.
Turn on your unit and ensure the Serial Data Format is set to "Garmin® Data Transfer" on comm port 1. You can find this setting in the Main Menu on the "Comm" tab's, "Port 1" tab.
The following files are found inside the driver download file.
