Thanks Wayne...so pretty close in cost. Would assume that a direct replacement would be no more than $400. I’m often surprised though.
Dang I'm confused now that I have had the new unit out on the water. I'll start by saying I have a Helix 10 G2N Mega DI unit at the bow and I love it. 2D and DI are both perfect on the unit. I asked Wayne earlier in the week if the XP 9 20 thru hull transducer that I had with my 1199 would work on the Helix 10 G2N if I decided to buy one and he said it would. When we found out the unit was different that a regular G2N and had the different transducer I was then informed that it wouldn't work and that I would need an XP 9 HW instead. I had already wired it up with the splitter that was on my 1199 so I just left it to try.
When I got to the lake this afternoon I decided to put the boat on the lake and see what I had. The SI looked awesome. The 2D worked fine but I wasn't sure what 2D I was seeing. I got the boat up on plane and the 2D worked fine all the way to about 50mph just like it did with the 1199. Biggest problem was the DI looked awful. Basically could see nothing. It was nothing like the DI on the bow. I unplugged the XP 9 20 to see if anything changed and got no 2D at all. I am pretty sure those transducers have SI/DI/2D don't they?
I know that's a lot of info but that was the first run with it for about 30 minutes this evening. I'll be out all day tomorrow.
I really appreciate Wayne for trying to be such a help to all of us on this board with this!

When you use a Y cable, the ONLY 2D you get is from the shoot-thru that is for 83/200 kHz. This is no connection for the HW piezo in the SI transducer so it is impossible to get 2D from it with that connection.
Since 200 kHz within the HW frequency spectrum that will work OK, but not as good as a HW CHIRP rated piezo.
Just like with the 1100 series unit, Side Imaging and Temp will come from the SI transducer. BUT if you did not change the Y cable to match a MEGA SI unit, you have no DI since the AS SIDB Y cable does not have a circuit for the DI piezo. If you want DI to work, you need the current Y cable 9 M SIDB Y.
Your 1199 does not have Down Imaging and got Down Imaging VIEWS via software blending the two SI pulses so the AS SIDB Y works with that unit, NOT the MEGA SI unit. The MEGA SI unit gets Down Imaging via a Down Imaging piezo in the SI transducer---gotta have a circuit for it.
If you want to get all functioning views for tomorrow, change the Connected Transducer setting to High Definition Side Imaging. Still will not be true DI.
Bottom line is if you want your new unit to function properly, get a XP 9 HW shoot-thru transducer and a 9 M SIDB Y cable.
BTW, you won't have the MEGA frequency with that setting, basically you will have another 1199.

Thanks Wayne, that helps a lot and makes sense. I didn't know there was a different Y cable that I needed to get. Just to clarify, in that post above, you are saying if I change the setting to High Definition Side Imaging I won't have the MEGA correct?

Spinnerb8 and Wayne, thanks for the info. Please let us know how the DI and 2D look tomorrow if you hook the new transducer up to the new unit without the Y splitter.

Seems like what is included is a standard G3N TD.
I have been using the G3N Si TD for months now and it works great on my G2N with 2.11 update.
You get the benifits of Dual Spectrum on 2d. You do not get + features on imaging tho.
Anyone have a link if they are still on special?
For those looking, Canelas got more of the Helix 10 in stock.

^^^ "Mark it zero". Don't get it.
Still in stock at Cabelas if anybody's interested
I have reviewed this thread in depth, but wanted to make sure of this due to a potential sale. Bought the Helix 9 G2N MegaSI last year, installed worked wonderfully, then saw the 10 this year and figured I could get it and swap the head units leaving the transducer in place (GIANT PITA to install with the transducer shield/saver). It seems as if the upgraded transducer is only compatible with this "new" G2N and wouldn't work with the existing 9 I have? I am asking only because I plan on selling the 9 and would hate to include the new transducer which may not be compatible with this unit. Any clarification on this would be appreciated!

Thank you both
granite sorry for the confusion regarding "mark it zero" signature.
No offense was meant towards you.
I will remove it.
