Hi there
I'm a super extreme novice with this stuff so I'm looking for help with my fish finder
I had a Navman fish 4200 that the screen was all blacked out on so I have bought a Navman fish 4350.
The 4200 had a black cable and a blue cable plugged into it.
The new 4350 I've purchased only has a socket for the black cable to plug in.
So as I have not taken it on the water yet my question is.
What does the blue cable do and do I need it or can I just leave it out ??????
Cheers for any advice

Pretty sure Black is the power cable and blue is the transducer cable input.

Some units also have a white which is for the optional fuel flow meters.

Check the unit again there can't only be the one input. Check there is not a protection plug in one of the other inputs which will need to be removed.

It's basically just a cover to stop dust/water ect getting into the input.
