for which it is designed, you will not be able to operate that unit. If
attempts to upload software fail, you may need to return the unit to Garmin
for service.
System requirements
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.
PC Interface Cable for your GPS unit. The PC Interface Cable may be
purchased through your local Garmin distributor or ordered direct from
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.
