Title: Have GPS Puck and Y COM Cable but Nothing Else
Post by: Consigliere on December 04, 2012, 10:58:22 PM: I am trying to use my 987c SI from a benchtop power supply so that I can export data etc in the comfort of home. Unfortunately you cannot access the NAV menus without a GPS puck installed. I have a GPS puck (GR 16/4) that does not have a cable attached, only the 3 wires (green, red, white) and I also have a Y COM cable from my other GPS kit that is permanently mounted in my boat.

Is there a way to get my GPS puck hooked up so that I can access the NAV menus with what I have or do I need to order a GPS cable? My DIY skills are suitable to making my own cable, just not sure how!

Alternatively, is there a way to access the NAV menus without a GPS puck connected?

Thanks

boat and export the data to an SD card.
You can then read the SD card from a computer (via HumminbirdPC
or Humviewer), or from another sonar unit.

I think without a GPS installed, your unit will be missing
lots of things:(namely views and menus).

I would think you could still view recordings on your
home system without a GPS installed, but I'm not
totally sure about that.

Greg would know.

Also, if you have a Navionics map chip, Navionics has some
software that you could download to your computer and look
at the maps.

I will try the simulator mode, hopefully that will work!

all Nav data to an SD card.
Then you could view it on a PC.

To get the unit into the forced Simulator mode:
- Power the unit on as normal but while it is still showing the “Humminbird 987c Si Combo” message; press the MENU button.
- You should have three or four menu options. Use the Up/Down Arrow buttons to highlight “Simulator”.
- Use the Right Arrow button to start the unit in this mode.

Personally I would use the forced Simulator mode.
