updating units with interlink
« on: October 14, 2011, 12:47:53 PM »
I have a 788 and a 798 interlinked. It is time to update since my last up date was a year ago (4.70 or close). I have downloaded the updates to my computer. Exactly what do I need to do and in what order to insure everything works when I am finished.

I would do the following:
 - Save the Nav Data (waypoints, tracks and routes) from both units.  Save the Nav data from each unit if it is different or just from one unit if both units share all Nav data.  This Nav data needs to be saved to your computer.  Before reinstalling this Nav data at the end of this procedure; you need to open it up in the HumminbirdPC program and re-save it to your computer as a *.gpx file.  We have seen where there has been corrupted Nav data that cause the InterLink not to work properly.
 - Delete the Nav Data off of the SD memory card so that it is blank.
 - Delete the Nav Data from both units and the InterLink.
 - Disconnect both units from the Interlink (and if you have them: WeatherSense, Nav Weather Receiver, Remote Sonar Link).
 - Perform a software update in both units.  Be sure that you only have one software update file on the SD card at a time; so if you are using only one SD memory card you will have to delete the software update file you used for the first unit before copying the software update file for the second unit to the SD memory card.
 - Reconnect the unit that was plugged into the Port 1 connector on the InterLink, to the InterLink again.
 - Power this unit on and allow it to update the InterLink.  Be sure to set it to participate in the InterLink system the way you want it to.
 - Power this unit off and reconnect the second unit.
 - Power both units on and set the second unit to participate in the InterLink the way you want it to.  Both units should now be working and you should be getting GPS on both units.
 - Reload you Nav data but only after opening it in the HumminbirdPC program and uploading it to the SD memory card once again.
