Default Interfacing Furuno Autopilot to Simrad MFD

I have a Furuno Autopilot that is currently interfaced with a 12” TZT2 Furuno MFD. I also have a Simrad NSS 16 Evo3 that I would like to interface with the Autopilot as well.
Can the Furuno and Simrad be interfaced with the Furuno Autopilot simultaneously?

I believe which ever unit is sending nav(route) data will work under the “Nav” auto mode, assuming both are on the same NMEA network.

Thanks for the reply.
Sounds logical. They are both on the same NMEA system. I haven't had a chance to try it with the SImrad but I will the next time I take the boat out.

How do you think your two MFD’s compare?

I used to be a die hard Furuno fan. My last boat had a Furuno VX2 NavNet system with a 10.4" Display. It was bulletproof. Fish finder worked good. The only complaint was that the menus were too deep and not that user friendly.
Fast forward to my current boat which I have been restoring. When it came to electronics I was all in for Furuno. I had a 12" and 15" MFD along with NXT radar and regular transducer and a 3D transducer and box. The radar was excellent but to say the fish finder performance was a disappointment would be an understatement. Continuous freezing, inaccurate readings etc. Furuno customer service sent a tech to go out on my boat with my installer. The tech had all sorts of test equipment. Long story short. Furuno bought back my 15' display and transducer.
I replaced the Furuno with a Simrad NSS 16" Evo3 with a chirp transducer. I couldn't be happier super accurate readings not only at slow speeds but while moving along at a good clip as well. I must say that I still like my Furuno Radar but I am now a Simrad fan and wish I would have gone all Simrad. My original setup is pictured.
PS. I still believe that Furuno makes excellent commercial units but their recreational line needs work. I have a feeling that their processors are under powered.

Frank,
I am just curious. Having been in the installation business for 30 years now I have found that when a sounder doesn't work, 99.9% of the time it is because of poor or improper transducer installation. I am mentioning this up because my personal boat has (2) TZT15" MFD's with a standard 50/200 transducer as well the Furuno 3D Black box and a 3D transducer exactly as you had. My two transducers are both thru-hulls and placed on opposite side of my boat. All work fine up to my boat's max speed of 38 knots.I can only see there being a problem if the transducer was installed wrong in the first place. Did you ever check to see if that was the problem. I also have the Furuno NXT radar and wouldn't give it up under any circumstances. I get to install everything and no other radar can even come close to working as well.

That was the first thing my installer said and he tested the Transducer theory by hooking up a temporary transducer to the black box. That transducer was on a pole which he hung over the side of the boat, of course we had to go slow but the temp transducer did the same thing. it showed atypical marks that were impossible to determine what they were along with freezing. When we told Furuno they immediately said it has to be some type of interference most likely from the engines. They sent a representative who made arrangements for one of their Japanese engineers to fly out with their testing equipment. We went out to sea for about 3 hours for testing. Furuno could not fix the fish finder and we made the deal for them to buy back the TZT2 15" and the transducer. The Simrad NSS 16 eve3 has a chirp transducer and it the best fish finder I have ever owned. Sorry to have to report that, as I said I am a loyal follower and was that to Furuno until this incident. I truly believe that their commercial equipment and stand alone fish finders are still excellent. Furuno NXT is TOP NOTCH. Since I use my boat primarily for fishing If Furuno would have bought back the complete setup I would have parted with the NXT and gone all Simrad so that I could have Interphased radar and autopilot with the evo3 fish finder. With that being said I'm happy with my setup plus I still have the black box and 3D transducer for the Furuno TXT2 12"
