Default Want to upgrade NavNet2 to chirp? on a 34 CV

Can I also change out one of the RDP149 screens units for a TZ touch? and leave the other? Yes, No?

What about the Tru Echo Chirp system? Is it good? I like the chirp ability to see through thermoclines yet show it all. We also do a lot of Tile fishing in 400 to 800 feet.

Solid glass hull with a flush mount 1 KW ducer in a flush pocket on the flat step bottom. Is that transducer no good and should I flush mount a chirp ducer.? Will a new one fit or should I just forget about it and shoot through the hull?
Just trying to get some thoughts on a spring upgrade. Just do not feel like re educating to Garmin. It took me too long to learn to use the furuno properly. We just do not use the boat enough to change out the whole system.

Thanks for any advice.

You can certainly change out a RDP-149 with a TZT unit, if it will fit. The TZT and TZT2 cannot utilize any of the earlier Navnet network sensors such as your radar and sounder module (unless you have the DFF1) I would certainly go witan flush mount through hull transducer for optimal performance, you can probably use your existing transducer with the DFF1 for non chirp sonar and get great results. Or if you go with the new TZT2 it has a built in sounder with post signal processing that should work with the existing transducer. If you have the b260 and want chirp you can install the b265, same housing but chirp technology. You will need the DFF-UHD sounder module as well.
Hope this helps

I'm in the same boat as Bly, so to speak.
Looking to upgrade soon and also have the Navnet VX2 with RDP-149 sounder unit and same glassed in 1KW xducer.I don't want to derail this thread but was wondering if the DFF1 would be "plug-n-play" with my current setup. I'm not interested in going to CHIRP but will be interested in the TZT2 MFD at some point.
If the DFF1 works with my xducer and also with the Navnet vx2 and improves sounder performance then it would seem to be a good upgrade that would let me install a new TZT unit when I'm ready.

UPDATE: I just read CMEBoston's post and he said that the TZT2 doesn't require a DFF unit since it has a built-in signal processor for the sounder. Hmmm, guess I need to do some research on the Furuno site and see which xducer it works with, etc.

It has a Furuno 10pin plug and will work with your existing 50/200 transducer

I was at the boat today and realized that the RDP-149 is the actual Navnet VX2 unit which I thought was the 1920C. The network sounder is a model ETR-6/10N.
I checked out the TZTouch2 details and it does have an internal fishfinder that works with various Furuno xducers - I just need to figure out what I have.

chances are what you have will work. Both have the 10 pin connector, both are 50/200 hz
