I just replaced my two year old Helix 12 MEGA SI G2N with a G3N model...There's some interesting upgrades, and the timing is good.

I also have a Helix 10 CHO G3N on the way, should see it by Tuesday.

To the issue:

With the G2N, I was running a 2D, high speed transducer so I could get depth readings at speed. I wound up not needing it because I was getting solid readings from the SI transducer up to the mid 30s...but it's was still my default 2D transducer.

Installed the G3N this afternoon...and the 2D doesn't show up in the network source screen.

Interestingly, a friend had the same issue with his G3N system, newly installed on a brand new Lund.

Any thoughts?

I've done all the normal restart/unplug-replug stuff...no joy.

50+ views and not even an idea?

You can always call Humminbird support and get them to help you.

Since there's so much help pouring out on this, I decided I'd do a little digging on my own.

 

A little digging, and some questions posted on apparently more knowledgeable forums indicated I should get my hands on a XNT 9 HW T transducer.

 

Did that, hung it, plugged it in, but no joy:

 

 

...still not showing up.  It's clicking, and I can hear it, but I don't see where the system is seeing it...

 

Kinda not happy with HB right now...

 

 

Try turning off 2D chirp.

Will do, thanks.  If I can find it.

 

I'll report back

Installed both new transducers in the same places, and at the same angles as the old ones...nailed it on the first run.  I have SI (no detail), DI, to 37 MPH, 2D as fast as I ran today.
