I have a Lowrance LCX15MT that I just removed form my boat. I have only used it for a front depth finder and have never used the GPS on it. I opened it to examine the chip inserts and found that it has two slots. The right side had a 16 gig chip labeled Texas and New Mexico. The left side was empty. I am not very computer savy and I don’t have a manuel for this model.The unit came with the boat which I bougth last year. It is an 04. The manuel that came with it is for a 330c/335cdf. On the back is a note writen by hand naming my model with version 2.3 April 22,2002. The question is what is the left slot for ?. I also read that these units can be updated to 3.6 or 3.7. How do you do that and will it improve the unit. It worked great for me and I will probably sell it but I don,t know what it can do or what it is worth. Any advice is appreciated.
