GPS 17N Software Version 2.60

------------------------------------------------------------
The software version is available via the PGRMT NMEA sentence 

The PGRMT sentence can be enabled by transmitting the following
command string the to GPS17N using a terminal program:
	
	$PGRMO,PGRMT,1<CR><LF>

If the GPS 17N is installed with a GMAP 2006/2010, the software
version can be obtained by completing the following steps:

	1.Press the MENU key to access the Main Menu.
	2.Press the DOWN ARROW key until the System tab is selected.
	3.Press the key below the "System Inf" caption. 
	4.The GPS 17N software version will be displayed on the 
	  screen labeled "Antenna:. 


------------------------------------------------------------
Warnings:

    If this software is uploaded to a unit other than the product for
    which it is designed, you will not be able to operate that unit.
	If repeated software upload attempts fail, you may need to return
    the unit to GARMIN for service.

------------------------------------------------------------
Notes:

Version 2.04 is the first widespread release software version. 
Version 2.04 was released in tandem with the GPS 2006/2010
products. 

Version 2.07 is the first widespread release software version
for standalone GPS17N sales.

Any units with software version 2.03 or lower will have
all nonvolatile memory erased when version 2.04 or later is 
loaded.

Upload Instructions - Serial Port Update:

Instructions for uploading the new software to your GPS17N using Microsoft
Windows 95 or later:

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

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

3.  Connect your unit to a free serial port (Com 1, 2, 3, or 4) on your PC. The
    user will need to build an appropriate cable to accomplish this.

4.  Power up the unit. Use a terminal program on your PC and connect to the 
    serial port. NMEA sentences should begin streaming by in the terminal 
    program.

5.  The unit will need to be changed from NMEA mode to a programming mode. To
    do this, transmit the following string using the terminal program:
		
			$PGRMO,,G<CR><LF>

    The unit will stop transmitting NMEA sentences and switch to the programming
    mode. At this point, disconnect the terminal program from the serial port.
	
6.  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 display will indicate "Software Loading...."
    The upload process should take 1-3 minutes to complete. When the upload
    is completed, the unit will reset itself and turn on normally. At this
	point, connect the terminal program to the serial port and NMEA sentences
	should be streaming by.

------------------------------------------------------------
Upload Instructions - USB Card Programmer Update. The GPS 17N
can be programmed in-situ via a GMAP 2006 or GMAP 2010 data 
card

Instructions for uploading the new software using a USB Card Programmer:

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

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

3.  Make sure a USB Card Programmer is connected to your computer, and that a
    data card is inserted into the programmer.

4.  Change to the directory in which you unzipped the files, (i.e., C:\GARMIN),
    and run the update program, program_card.exe.  Select "Card Programmer"
    and click "OK" to begin the software upload.

5.  Remove the data card from the USB Card Programmer.  Make sure that your GPS
    unit is powered on and insert the data card into the unit to begin
    uploading the software to the unit.  During the upload, the display will
    indicate "Software Loading...".  The upload process should take 1-5 minutes
    to complete.  When the upload is completed, the unit will reset itself and
    turn on normally.
