Ive got a question for those of you that have installed an lcx-28c or similar lowrance unit.. First off ive hooked up everything and put a switch in both the network line and the main power line for the unit, both are fused and when i test them with my power meter i am getting power though both switches (so i know they are both good). The network cable has 2 negatives and one positve, the main power line simply has a positive and negative. Heres my problem.. the unit says "GPS module not responding". My sonar is working fine and my unit has power, but something is up with my GPS.. Ive installed the GPS module on a white plastic "pole" (the cone shaped one) and simply plugged the line together and then plugged it into the back of the unit, seemed to be self explainatory. Now as for the "data cable" (the one with all the colors) im assuming i wont be using this cable as i dont have any special features or sonar amplifiers used, so nothing on that line is connected. any ideas before i call lowrance for some help with it?
