one is a SeaNav 5 and the other says Lowrance GPS, both worked, I replaced the older one and when i went up to mount it, i found the old cable was broken at the base of the connector, didnt check it before because it looked fine. I guess you need to find out from lowrance if its compatible, it is the rectangular shaped module, not the round type like i have for my global map 3000MT. If its compatible, you can have either for 50 bucks, i paid 300 at west marine for the newer one 2 seasons ago.
