I lost my Gps on my 797. It doesn't say no connection or anything like that, just no GPS anywhere. Not when I scroll the screens or when in the menu. Cleaned connections and such but know luck. It is on my simulator mode though, but didn't notice if it was showing a correct reading while in simulator. I have use my unit in the house with no puck connected to add waypoints, I don't know what it could be. Is it my puck or what. Please help!!
my 898 did that this past spring, i had to send it back and they (humminbird) fixed it. i too thought/hoped that is was the connection.
Does the status screen say the GPS is "connected" ....??
Is the GPS plugged directly into the unit or thru an Interlink...??
Can you try your unit on someone else's boat with a 797c...??
Can you try someone else's 797c on your boat...??
(I think I remember Greg saying to only try this with a AS GR16 unit..)
Did this happen soon after any changes to your setup...?? Software update..?? Moving antenna..?? 1st use after long term storage...??
Rickie
My screen doesn't say anything with "GPS" in any form
It is plugged directly into unit
I don't know anyone off hand that has a 797
Oh yea, I have recently moved the puck
Try this...
Power on the unit..
While the welcome screen is showing... Press "Menu" on the unit face...
Of the 3 options... Cursor down to "System Status"..
Cursor right to enter "System Status"...
Press "View" on the unit face to get to the "Accessories" screen...
Does the GPS show "Connected" or "Unconnected"...??

Rickie,
You are right on with only using a GR16 GPS Receiver with the 797 units.
bttmline,
Try what Rickie suggested and see if the unit is showing the GPS Receiver as “CONNECTED” or “UNCONNECTED”. If “UNCONNECTED” try checking the NMEA pigtail wire for a short. This is the shorter (12 inch) second wire that comes out of the GPS Receiver connector. It should have a small black cap on the end of it. Remove this cap and separate the Red, White and Black wires. Power your unit on again and see if the GPS Receiver is shown as “CONNECTED” and starts to work or not. If it does, trim and seal the wires so that they cannot short to each other or anything on the boat. If it does not start working, then there is no way to know if the problem is in the GPS Receiver (“puck”) or in the unit itself. You could take the chance that the problem is in the GPS Receiver (as it usually is) and buy a new one or send yours into Humminbird to be fixed or contact Humminbird (1-800-633-1468) and see about getting both your unit and GPS Receiver in to be fixed.
Well it says unconnected, so i did trimmed the NMEA tail back and separated the wires to insure there was no short. Still says unconnected so I guess I need to get a new one or get the old one checked. What does it cost to have it repaired or is it better to just by a new one??
Before you send it in to HB....
Check the male pins in the connector and the female pins in the unit...check for corrosion or missing pins...
Try bending the pins out "ever so slightly"...
Take the GPS connector (and the power wire connector) (you will not need the xducer for this test) out of the mounting bracket and plug them directly into the unit...wiggle the connector while watching the "Accessories" screen to see if you can get the unit to recognise the puck...

As Greg is following this thread, I'll input a question I don't know myself...
Can the 797 be tested (and/or operated) on the AS GR50...??
Rickie
Maybe Rickie.
It all gets back to when the GR50 was manufactured and just how much current that particular 797c2 unit can source for the accessories. The current GR50 uses a bit less power while operating versus the first ones we made (the original GR50’s were not designed to be used with the 797c2 units). Some 797c2 units may be able to provide enough current to operate a GR50 but some cannot. If the unit cannot than the unit will burn out the accessory power circuitry and it will have to be repaired (~$200) or replaced.
The cost to repair a GR16 is listed as $60.45 on the Humminbird web site:
Humminbird: America
A repaired GR16 should have a 90 day warranty on it.
New AS-GR16’s are listed for not much more than that on the Humminbird site:
AS GR16 :: Humminbird
A new GR16 should have a 1-year warranty on it.
Thanks Greg.. I'll make a note of that so I can advise people to only test/operate the 797 with the AS GR16....
Bttmline... Have you been able to get a puck connection by taking the cables out of the mounting bracket and plugging directly into unit...??
Rickie
yes I have and still nothing. I suppose I will buy a new puck.
Now, Greg, My unit came with a gr50 so do I have to replace it or can I purchase the 16?
bttmline,
Did you buy the 797 unit new and it came with a GR50 GPS Receiver? I did not think that we started making the GR50’s until after the 797’s were replaced by the 798 units. I would not take the chance and would recommend getting the GR16 GPS Receiver, just to be on the safe side.
Yes it came with a 50. But I will gladly by a 16. Thank you for all your help!!
