After doing more research I found my unit is only capable of 455 kHz,
Thanks to everyone who tried to help.

Definitely in Custom mode, thanks anyway.

Software is up to date, did it a few days ago, thanks anyway

I should clarify, it does say 2D CHIRP Frequency but does not say “2D CHIRP Frequency Spectrum” as I say on line .

Thank you for getting back to me, system was bought new with Transducer. I made no changes

Thank you,

I ended up with two windshields that were made for a different boat but I was able to make it work for me. Thanks again.

I have a ’98 V177 Eagle as well. The way I described will work for sure. Just make sure the plug on your TM cord is wired correctly. It’s really not hard once you open the plug up you will see.

Hey Royalfish
As I think about it I am wondering why I need the TM cord if my trolling motor is 12V and I have 12V coming from the socket?

Thank you, I will test this out.

There may be other ways to work this, but here is how mine is setup.

You will need 2 batteries. Hook Black 1 and Red 1 to Battery 1. Hook Black 2 and Red 2 to Battery 2. This will send 12V to the socket in the bow and 12V to the stern socket. You will need a Marinco 12/24V plug to wire to the end of your trolling motor cord. Inside the plug you will have to wire to the 12V connection and not the 24V. The plug has an internal jumper that can make 24V in the plug.

Thanks for the reply. 12v Trolling motor in the front. It was a Private sale. I have tried contacting the previous owner but he does not respond.
