I have two 997 units, one at console and one at the bow. Both units are connected with an Interlink with a GR50 GPS puck connected to the GPS port on the Interlink and both units show connected to the Interlink and share waypoints and the side imaging works. The console 997 unit shows on the GPS Diagnostic View as connected to Interlink GPS and works fine. However, the bow 997 unit, which is the new unit I just purchased, shows on the GPS Diagnostic View as connected to Remote Internal and I can't get a GPS position fix. If I move the bow 997 back to the console position I get the same result on GPS Diagnostic View as connected to Remote Internal. I was assuming that I could simply go into the Nav menu and find the GPS Receiver Override selection at the bottom of that menu, and change it to Interlink GPS, but the GPS Receiver Override menu selection does not appear. I understand that may not come up unless two GPS devices are available, but not sure.
Any help on how I can change the bow 997 from Remote Internal to Interlink GPS?...I'm stuck
Update:
--I connected a separate GR50 puck directly to the bow unit using its NMEA cable while disconnecting the bow unit from the Interlink. The bow unit finds this separate GR50 fine (as an External GPS) and gives GPS position.
--I then disconnected everything from the Interlink and only connected this separate GR50 to the Interlink and only connected the bow unit to the Interlink using a separate COM cable. The Status View says the GPS is connected but the GPS Diagnostic View says its looking at Remote Internal and doesn't give any GPS position.
--I then substitute my console unit in the above scenario and it finds the GPS through the Interlink and gives GPS position no problem.
So it seems my bow unit will work if I connect a GPS unit directly to it, but won't work if connected through the Interlink whether I use the boat's installed cables and existing GR50 or use a separate GR50 and separate COM cable.
Any ideas? Software was updated two days ago to 5.8x

Solved my own issue, so wanted to share the solution:
After restoring defaults (under Setup menu) on the bow 997 unit, the 997 starting seeing the Interlink GPS, no problems!!!

I am not sure when HB added restore defaults to their update code so you may have gotten in caught in a process.
It is always a good idea to restore defaults befolre updating and right after.
Thanks for the feed back. This may help someone else..

Yeah, thanks, talking to my son, he did follow the process when updating the software, he backed everything up and restored defaults before updating the software. He said both units worked at first and he changed the bow unit to Remote Internal (he said he misunderstood the choices) and that must have got us caught in a state/mode that didn't allow us to either see the GPS Receiver Override menu again and therefore change it to "Interlink GPS". By selecting Restore Defaults must have freed up the unit to beginning automatically recognizing the Interlink GPS.

I have seen several issues freed up by a restore default.
Wouldnt it be nice to have a hard factory restore also.
(it is on a wish list)
That way we might not have to send in to HB for service.
Glad you are back in business.
