GARMIN GPS III Software Upgrade Information
Software Version 2.10
http://www.garmin.com
------------------------------------------------------------
WARNING:
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 software upload 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 GPS III using Microsoft
Windows 95/98/NT:
1. Download the appropriate self-extracting archive file for your GPS III onto
your hard drive.
2. Unzip the files in the archive by running the downloaded executable file.
3. Connect your GPS III to a free serial port (Com 1, 2, 3, or 4) on your PC
with a PC interface cable.
4. Turn on your GPS III and ensure that the Interface 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 GPS III's display will indicate "Software
Loading...." The upload process should take 3-10 minutes to complete. When
the upload is completed, the GPS III will reset itself and turn on
normally.

Changes Made From Version 2.09 to 2.10:
1. Added MGRS position format.
2. Improved messages and terminology relating to DGPS input.
3. Modified the arrival alarm to give approach notification at intermediate
route waypoints when set to "On".
4. Adjusted times recorded in track points by applying leap seconds.
5. Corrected handling of long route and track log names in messages when in
portrait display mode.
6. Corrected problem related to revisiting the Routes page after changing the
display orientation from portrait to landscape.
7. Corrected problem with starting a goto to an invalid waypoint.
------------------------------------------------------------
Changes Made From Version 2.08 to 2.09:
1. Adjusted the definition of the Hu-Tzu-Shan map datum.
2. Corrected baud rate of output in "RTCM/Text" serial interface mode.
3. Corrected handling of negative altitudes in simple text output format.
4. Corrected position label when certain grids are selected for the position
format.
5. Corrected flaws with waypoint storage and map drawing when using a map
datum other than WGS 84.
6. Changed software version number from "2.08" to "2.09."
------------------------------------------------------------
Changes Made From Version 2.07 to 2.08:
1. Corrected orientation change processing when backlight/contrast page
overlays the database disclaimer page.
NOTE: This was a minor aesthetic problem which was introduced along
with the backlight/contrast adjustment changes in version 2.06.
2. Corrected waypoint Spell'n Find search behavior for names containing
whitespace.
NOTE: Previously, a waypoint with a name like "A B" could not be
found by Spell'n Find search if the waypoint "A" also existed.
3. Corrected accuracy circle display switch initialization.
4. Increased maximum backlight brightness.
5. Added New Zealand grid position format.
NOTE: This has added "New Zealand" to the available position formats
on the Position setup page. Selecting "New Zealand" automatically changes
the map datum to "GEOD Datm '49." This is done because the New Zealand
grid conversions use constants derived from the datum. As such, the grid
is not accurate unless the datum is set appropriately.
6. Added new interface format for simple output of position, velocity, and
time text.
NOTE: On the Interface setup page, there have been two changes to the
format selection list. "RTCM In" was changed to "RTCM/Text" and "Text Out"
was added. Baud rate for this output is adjustable and defaults to 9600
baud (8 data bits, no parity and 1 stop bit). See the following section
for details on this output format.
7. Updated copyright date displayed during power-on.
8. Changed software version number from "2.07" to "2.08".
------------------------------------------------------------
New Simple Text Output Format:
The simple text (ASCII) output contains time, position, and velocity data in
the fixed width fields (not delimited) defined in the following table:
FIELD DESCRIPTION: WIDTH: NOTES:

Sentence start 1 Always '@'
----------------------- ------- ------------------------
/Year 2 Last two digits of UTC year

| Month 2 UTC month, "01".."12"
T | ----------------------- ------- ------------------------
i | Day 2 UTC day of month, "01".."31"
m | ----------------------- ------- ------------------------
e | Hour 2 UTC hour, "00".."23"
| ----------------------- ------- ------------------------
| Minute 2 UTC minute, "00".."59"

\Second 2 UTC second, "00".."59"
----------------------- ------- ------------------------
/Latitude hemisphere 1 'N' or 'S'

| ----------------------- ------- ------------------------
| Longitude position 8 WGS84 dddmmmmm with an implied
P | decimal after the 5th digit
o | ----------------------- ------- ------------------------
s | Position status 1 'd' if current 2D differential GPS position
i | 'D' if current 3D differential GPS position
t | 'g' if current 2D GPS position
i | 'G' if current 3D GPS position
o | 'S' if simulated position
n | '_' if invalid position
| ----------------------- ------- ------------------------
| Horizontal posn error 3 EPH in meters
| ----------------------- ------- ------------------------
| Altitude sign 1 '+' or '-'
| ----------------------- ------- ------------------------
| Altitude 5 Height above or below mean
\ sea level in meters
----------------------- ------- ------------------------
/East/West velocity 1 'E' or 'W'
| direction
| ----------------------- ------- ------------------------
| East/West velocity 4 Meters per second in tenths,
| magnitude ("1234" = 123.4 m/s)
V | ----------------------- ------- ------------------------
e | North/South velocity 1 'N' or 'S'
l | direction
o | ----------------------- ------- ------------------------
c | North/South velocity 4 Meters per second in tenths,
i | magnitude ("1234" = 123.4 m/s)
t | ----------------------- ------- ------------------------
y | Vertical velocity 1 'U' (up) or 'D' (down)

----------------------- ------- ------------------------
Sentence end 2 Carriage return, '0x0D', and
line feed, '0x0A'
----------------------- ------- ------------------------
If a numeric value does not fill its entire field width, the field is padded
with leading '0's (eg. an altitude of 50 meters above MSL will be output as
"+00050").
Any or all of the data in the text sentence (except for the sentence start
and sentence end fields) may be replaced with underscores to indicate
invalid data.
