Question about Lowrance LGC-2000 GPS Unit GPS Receiver
I've had this problem for 3 of 4 years. Lowrance support was no help just sold me a new antenna, which eventually had the same problem. Fix, is to buy a Garmin.

had same problem with lms337. i had upgraded the unit but had not upgraded the lms2000 gps module. i was turning the isolator on in the boat which powers up gps module, if the lms337 is not powered up as well the gps unit goes to sleep. the upgrade fixes it by checking that the unit has not been turned on periodically. otherwise as soon as you power up gps module also turn on lms337. lowrance product support sorted this for me.

Go to lowrance's website and run through their set up tutorial / instructions for the unit, there is also a software upgrade you can do online for the unit.

Before you give up on the LGC-12S you have now though, try plugging the LGC-12S right into the LCX-15CT without an extension cable. If the module not responding goes away...you just need a new extension (GPSX-25G p/n 99-46).
The power cable has a set of yellow, blue, orange, and bare data wires. If these wires short together, you can get the module not responding error.
If all that doesn't help...the LGC-12S is bad.
The LGC-12W p/n 112-06 will work with the LCX-15CT. You probably get this at many marine electronics dealers or go to lei-extras.com and buy it straight from Lowrance. They cost $229 so you might want to shop around putting that money into a whole new system altogether.
Make sure you have the latest software updates if you get the newer LGC-12W. These can be downloaded at http://www.lowrance.com/en/Downloads/Product-Software-Updates/
Let me know if you need more help.
