switching lowrance units...help

I have been on hold with lowrance for over an hour trying to get some help. Does anyone know a possible answer to my question. I have an old X70A unit. I want to try my friends LMS 332C. I would have to drive 2 hours to get it so will it hook up to my connections? I know the gps won't work. It sounds like both connections are grey. This may be impossible to answer without trying the other unit, but I have been amazed over the years of the knowledge on this site. Thanks

if you can't find your answer here, there is a sonar/gps installation and question forum at bassboatcentral.com. Someone ther can answer. Also, they have a few lowrance people on there that can answer

I'm thinking the 332C has blue connectors so no it will not hook up to your current gray connections.

No it will not hook up.
