LCX-27C GPS Module Not Responding

I just installed my new LCX-27C on the boat ran the GPS module to a open acessorie switch in my boat. Fired it up and the depth finder works but I am getting a GPS module not responding message. The only thing I am not sure of is the "sheilded wire" I put with the negitive wire on the acessorie switch. Does this have to goto its own ground?

The shield should go along with the Black wire to Neg. Not sure how you have it, as you mentioned the neg wire on the switch? If you are certain you have the NMEA networked powered, go into the System menu, and look for NMEA devices. You may need to update the firmware for the GPS, the head unit, or both. Get these from www.Lowrance.com. Where are you located?

Here is the link from Lowrance that explains the connections required. http://www.lowrance.com/upload/Lowrance/Documents/Manuals/LGC-2000a...
