Hummingbird 787c2 ?

[joeyd50]

I have one I just put one on my boat, I had to buy a transducer and a GPS antenna. The FF works fine but the GPS test keeps saying GPS unconnected. I checked with Hummingbird and the Antenna is correct. The AS-GR16 antenna came with a short Y wire that I did not use. I just ran the wire from the antenna to the back of the unit. Do I need something else to get this working?
Thanks
Joe

The GPS antenna on my HB 597ci HD DI is built in, might post your question over at https://forums.sideimagingsoft.com/index.php there is a wealth of information there including some people from HB

Hope you get it figured out.

I went thru manuals on both units. Only thing I could find is line in antenna manual saying refer to manual of depth finder for settings, but I could not find anything about it in that manual.
I am guessing one has to change some settings in depth finder.

Also I saw that it has some wires for output to aux device red/12v, blk./ground, and white/signal. You may have already, but I would make sure those are taped off an insulated from each other.

make sure the antenna has a clear and unobstructed view of the sky in a 360* view. I have a 788 ci HD and I got the "no gps fix" message for 5 minutes this past saturday. It finally locked on and was fine from there. I plan on raising my HU up about 12" soon to give it a better view of the sky, and hope it will do away with the "donut" issue as well.

I don't even get no GPS fix or the Satellite page. I get GPS unconnected.

Does it have an SD car slot? If so you can do the update from the SD card.

 

[joeyd50]

Yea it has the SD slot, I logged on to my account with Hummingbird, there is my 787c2 I click download file with my SD card in the reader, I go to my unie, start it up hit restore defaults confern the restore put the card and nothing happens. Its supposed to as me if I want to install software updates but it doesn't.

 

[joeyd50]

I finally got the new software on my 787c2, I still don't have GPS, it still says GPS Unconnected. I'm still open to suggestions on that GPS issue, any help is appreciated.
Thanks

Here's a possibility, the GPS antenna that you bought is defective. Do you know anyone with the same unit you can try it on? Can you return it to where you bought it and get another one?

I have gotten good results on this forum.

This one runs a close second for Humminbird products

Sounds like your wires are bad - I had the same problem and it turned out that the wire that connects the GPS was bad - changed it out and no problems

 

[River]

You didnt cut and splice any wires did you ?.....River

 

[joeyd50]

I didn't cut any wires, the guy that sold me this unit has another one he's going to let me try.

 

[nlester]

Did you get your GPS working???

 

[joeyd50]

Did you get your GPS working???

Not yet, The guy with the other unit is a friend of my son's, I'm just waiting for him to drop off the other unit to try. I have another question, Does anyone know what GPS antenna a Humminbird 595c takes? I looked eveywhere and I can't fine it.
Thanks

The AS GR16 is the one for the 595c, my son has a 595c, I tried my 787c2 on it and it came up GPS Unconnected, I put his 595c 0n my boat and it came up GPS connected, so there's nothing wrong with my Antenna.
Thanks for all the help
