The following are required to upload the software update into your
Garmin GPS unit:
- IBM-compatible PC (386 or higher microprocessor running DOS, Windows
3.1x, Windows 98, Windows ME, Windows 2000, or Windows NT
4.0) with an available Com 1, 2, 3, or 4 port.

our Online Store.

| Instructions for
uploading the new software to your unit: |
|
|
|
- Download the appropriate self-extracting zip file for your GPS unit
into a directory on your hard drive. (i.e., c:\garmin).
- Unzip the files into this directory by running the downloaded executable
file (.exe).
- Connect your GPS unit to a free serial port (Com 1, 2, 3, or 4) on
your PC with a PC Interface cable.
- Turn on your GPS unit and ensure the Interface setup is set to "GRMN/GRMN
HOST," "Garmin," or "DATA TRANSFER SLAVE" mode, depending on the specific
Garmin model.
- From the DOS prompt, change directory (CD) to the directory in which
you unzipped the files, (i.e., c:\garmin), and run the update program:
updatesw.exe.
The upload process should take approximately 3-10 minutes to complete.
When the upload process is complete, the unit will reset itself and turn
on normally.
