GARMIN GPS76 Software Upgrade Information
Software Version 2.20
http://www.garmin.com
------------------------------------------------------------
WARNINGS:
If this software is uploaded to a GPS unit other than the product for
which it is designed, you will not be able to operate that unit.
If the upload software fails, verify that you have good batteries installed
and try again. If repeated upload attempts fail, you may need to return
the unit to GARMIN for service.
------------------------------------------------------------
Instructions for uploading the new software to your GPS76 using Microsoft
Windows 95/98/NT:
1. Download the appropriate self-extracting archive file for your GPS76 onto
your hard drive.
2. Unzip the files in the archive by running the downloaded executable file.
3. Connect your GPS76 to a free serial port (Com 1, 2, 3, or 4) on your PC
with a PC interface cable.
4. Turn on your GPS76 and ensure the Serial Data Format is set to "GARMIN".
You can find this setting in the Main Menu under "Setup".
5. Change to the directory in which you unzipped the files, (i.e., C:\GARMIN),
and run the update program, updater.exe. Select the appropriate serial
port and click "OK" to begin the software upload.
During the upload, the GPS76's display will indicate "Software Loading...."
The upload process should take 3-10 minutes to complete. When the upload
is completed, the GPS76 will reset itself and turn on normally.

Changes Made from Versions 2.10 to 2.20:
1. French translation update.
------------------------------------------------------------
Changes Made from Versions 2.09 to 2.10:
1. Fixed problem with changing elevation units. Now able to change to meters
without having to restart the unit.
2. New French translations.
------------------------------------------------------------
Changes Made from Versions 2.08 to 2.09:
1. Eliminated possible shutoffs when repeatedly finding Cities or Points of
Interest.

the route waypoint transitions to Manual. When set to Manual, routes will
transition to the next waypoint only when instructed to do so by the user.
5. Added a Setup NMEA output item to the Interface setup page menu when the
Serial Data Format is set to NMEA. This allows setting the following for the
NMEA output: the precision of the minutes field for lat/lon, the waypoint
identifier format, and which groups of sentences to transmit. These
settings allow compatibility with a wider range of NMEA-driven products
including some older marine autopilots.
