GPS 16 Software Version 2.80 ------------------------------------------------------------ The software version is available via the PGRMT NMEA sentence The PGRMT sentence can be enabled by transmitting the following command string the to GPS16 using a terminal program: $PGRMO,PGRMT,1<CR><LF> ------------------------------------------------------------ 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 2.03 is the first widespread release software version. Any units with software version 2.03 or lower will have all nonvolatile memory erased when version 2.04 or later is loaded. ------------------------------------------------------------ Change History Version 2.70 to 2.80: 1. Fixed potential loss of user settings in version 2.70. 2. Changed software version to 2.80. ------------------------------------------------------------ Change History Version 2.60 to 2.70: 1. Added ability to turn low speed velocity masking on and off via a NMEA command. 2. Changed software version to 2.70. ------------------------------------------------------------ Change History Version 2.50 to 2.60: 1. Added a new configurable feature called PPS Auto Off Mode that is disabled by default. Enabling this feature will turn off PPS output when the GPS fix is lost. Once a new fix is obtained PPS output will resume as normal. 2. Corrected the sign on integrated cycles and carrier phase data in the RCV CPO message. 3. Changed software version to 2.60. ------------------------------------------------------------ Change History Version 2.40 to 2.50: 1. Improved SBAS search and selection process. 2.

Improved EPH during transition from non-differential fix to a differential fix. 3. Added ability to turn position averaging on and off via a Garmin or NMEA command. 4. Allow vertical filter to be disabled via the PGRMC sentence. 5. Enhanced first fix processing. 6. Changed software version to 2.30. ------------------------------------------------------------ Change History Version 2.10 to 2.20: 1. Improved non-volatile memory storage of WAAS/EGNOS ionospheric mask corrections. 2. Changed software version to 2.20. ------------------------------------------------------------ Change History Version 2.09 to 2.10: 1. Improved WAAS/EGNOS satellite selection algorithm to select the satellite with the most beneficial corrections given the unit's current position. 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. 2. Changed software version to 2.10. ------------------------------------------------------------ Change History Version 2.08 to 2.09: 1. There were no functional changes made for this release. Modifications were made for manufacturing purposes only. 2. Change software version to 2.09. ------------------------------------------------------------ Change History Version 2.07 to 2.08: 1. Added automatic position averaging when stopped. 2. Obsoleted position pinning. Position pinning remains off regardless of the PGRMC1 sentence command. 3. Fixed problem with saving unit position in nonvol upon first fix. 4. Change software version to 2.08 ------------------------------------------------------------ Change History Version 2.06 to 2.07: 1. Added support for ephemeris download. 2. Fixed problems where leading zeros were not being transmitted in certain fields of GPRMC and GPVTG. 3. Improve eph estimate for WAAS DGPS fixes. 4. Changed software version to 2.07 ------------------------------------------------------------ Change History Version 2.05 to 2.06: 1. Addressed problem where NMEA sentences could become intermittent and unreliable when tracking two WAAS satellites simultaneously. 2. Addressed problem where an "extra" PPS pulse sometimes occurred in marginal signal environments. 3. More work on problem where the unit sometimes reported an incorrect date and time in marginal signal environments when PPS is enabled. 4. Changed software version to 2.06. ------------------------------------------------------------ Change History Version 2.04 to 2.05: 1. Fix problem where unit sometimes reported an incorrect date and time in marginal signal environments when PPS is enabled. 2. Changed software version to 2.05. ------------------------------------------------------------ Change History Version 2.03 to 2.04: 1. Improve velocity accuracy when PPS is enabled. 2. Changed software version to 2.04. ------------------------------------------------------------ Upload Instructions - Serial Port Update: Instructions for uploading the new software to your GPS16 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. It is recommended that you unzip the files to the default location of C:\Garmin, but you can browse for a different location. 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. If you unzipped the files to C:\Garmin follow option 1 below. If you unzipped the files to another directory follow option 2 below. Option 1: a) Navigate your browser to the C:\Garmin folder and run the SNSRCFG program by clicking on the SNSRCFG.exe file. Make sure "GPS 16/17" base model has been selected and click "OK". b) Either select Config-Update Software from the menu bar or press F12 to update the software. Normally, you will see a confirmation window indicating that you have connected to the unit. If the connection confirmation window does not appear, there are two possibilities: i) The GPS16 is not properly connected to your computer. Click "Cancel". The update program will not find the GPS16 and will fail. Verify the serial connections, cycle power on the unit, and try again. ii) The unit may be in Garmin (update) mode. In this case, click "Cancel" to continue with the update. c) A browser window will open and default to the folder C:\Garmin. You may now browse for the correct region file to upload. The correct region file will be named 017600000XXX.rgn, where XXX is the version number of the software you wish to upload. Select region file and click "Open". d) At this point, the Garmin software update program, updater.exe, will start. Updater will prompt you to select the appropriate serial port. Click "OK" to begin the software upload. Option 2: a) Run SNSRCFG by clicking on the SNSRCFG.exe file. Make sure "GPS 16/17" base model has been selected and click "OK". b) Either select Config-Switch to Garmin mode from the menu bar or press F11 to switch your unit to Garmin (update) mode. If the unit is in NMEA mode you will see a confirmation window saying "Connection Success". If the connection confirmation window does not appear, there are two possibilities: i) The GPS16 is not properly connected to your computer. Verify the serial connections, cycle power on the unit, and try again. ii) The unit may already be in Garmin (update) mode. Proceed to step c. c) 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. 5. 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, click the connect button (or select Comm-Connect from the Menu bar). If you select view-NMEA Transmitted Sentences the NMEA sentences should be updating on the screen. NOTE: If, for any reason, updater does not completely execute and terminate normally, the GPS16 system software may be corrupt and the unit will remain in Garmin mode. If this is the case try the following: 1. Try to switch the unit back to NMEA mode (press F10 or select Config-Switch to NMEA Mode). 2. Check to see if the unit is transmitting NMEA sentences. If the unit is transmitting sentences, verify the software version number via the PGRMT sentence. If the GPS16 is not transmitting sentences or the version number is not correct, you must reload the software starting with step 4a above.Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
