Re: My LCX-15 Lowrance is not recog. my Gps module
I have a LCX15 MT w/GPS. You definitely need 12V at the head unit according to Lowrance, re-check voltage and connections. You don't need to enter any info or have a MMC/SD card in the slot. Once your unit acquires satellite lock it will set the time. If you're using the extension cable, try without it, direct between head unit and receiver. Make sure the 4 data wires that are combined into your power lead aren't touching anything/each other. Should be individually taped or insulated. You could try a hard re-set of your unit. This should return your head unit to the way it was upon leaving the factory. Afterwords you'll have to reset your user preferences. With everything connected, hold your zoom out and zoom in buttons in while powering up the unit. Continue holding all three buttons in until the US map appears, then release. Depending upon age, it might help to update your unit's software. Ver# 3.60 is available. You'll need a memory card & reader to do so. Mine is around 2 years old and I have kept it current, every update has been an enhancement/worthwhile. If after powering up you don't get the error on screen be patient, it will take awhile initially. Make sure the receiver has a clear, unobstructed shot at the sky. Let me know how it goes, email if you like. As you can see from my post, I've "been there, done that". Hope this helps.<br />JD
