GARMIN GPSMAP76 Software Upgrade Information

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 GPSMAP76 using Microsoft
Windows 95/98/NT:

1.  Download the appropriate self-extracting archive file for your GPSMAP76
    onto your hard drive.

2.  Unzip the files in the archive by running the downloaded executable file.

3.  Connect your GPSMAP76 to a free serial port (Com 1, 2, 3, or 4) on your PC
    with a PC interface cable.

4.  Turn on your GPSMAP76 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 GPSMAP76's display will indicate "Software
    Loading...."  The upload process should take 3-10 minutes to complete.
    When the upload is completed, the GPSMAP76 will reset itself and turn on
    normally.

1. Fixed shutoff problem with certain European tides.

------------------------------------------------------------

Changes Made from Versions 3.70 to 3.80:

1. Corrected problems with European tides.

------------------------------------------------------------

Changes Made from Versions 3.60 to 3.70:

1. Improved non-volatile memory storage of WAAS/EGNOS ionospheric mask corrections.

2. Reduced delays in acquiring a position when using differential GPS.

3. Added Canadian tide support.

------------------------------------------------------------

Changes Made from Versions 3.50 to 3.60:

   Units will not use a WAAS/EGNOS satellite if the unit's current position 
   is outside of a given WAAS/EGNOS satellite's service volume.

4. Added new "Distance and Speed" unit. The new unit is "Nautical (nm, kt, m)".
