Installation Instructions

  1. It is recommended that you disable screen savers or other programs running on your PC while you go through the update process. Disruptions to the update process may render your GPS inoperable. If the transfer is interrupted, turn off the GPS and then turn it back on. Reboot your PC, go to step #9 and attempt the download again. GARMIN is not responsible for failed downloads of operating software to the GPS and factory resetting the GPS unit will fall under our Flat Rate Repair Policy.
  2. Click on "Download" and choose to save the file to your computer.
  3. Choose a location where you can easily locate the file by saving it to a location such as the "My Documents" folder or to "C:\".
  4. Once the download is complete, go to the location where you saved the file.
  5. Locate the downloaded file and double-click on it. This will launch the Win-Zip Self Extractor. This program compresses the data to allow for a faster download of the needed files.
  6. A program window will appear asking you where to "Un-zip" the files. This is by default C:\Garmin. You can change this location if you like. Be sure to note where the un-zipped files are going to allow you to find them!
  7. Click on the button labeled "Un-zip".
  8. Once the un-zip process is complete, click on the "Close" button to exit the Win-Zip Self Extractor.
  9. Click on the "OK" button on the Updater program window to start the data transfer.
  10. 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.
  11. Power up the unit.
  12. 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 'GPS15 H/L' 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 GPS15 is not properly connected to your computer. Click 'Cancel'. The update program will not find the GPS15 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 021700000xxx.rgn, where XXX is the version number of the software you wish to upload. Select region file and click 'Open'. d) A browser window will open and prompt for an update program. Select the Garmin software update program, updater.exe. Updater will start and prompt you to select the appropriate serial port. Click 'OK' to begin the software upload.
  13. Option 2: a) Run SNSRCFG by clicking on the SNSRCFG.exe file. Make sure 'GPS15 H/L' 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 GPS15 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.
  14. 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.
  15. NOTE: If, for any reason, updater does not completely execute and terminate normally, the GPS15 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 GPS15 is not transmitting sentences or the version number is not correct, you must reload the software starting with step 12 above.
