Here is the manual.
Try page 212.
Hope this helps.

Check the reverse protection diode and capacitors on the unit's power circuit.

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.

I had the same problem with my handheld Lowrance Hunt C. After installing the card and locking it in place, I had to slide the card "out" toward the locking mechanism. It barely moves, but worked after that. Whenever I load the card, I now slide it out or wiggle it and it works every time.

I have a owners manual i can copy for you if you haven't found one yet. It old and but mostly legible Matt
