Updating from NN3

[backman]

Can I upgrade from NN3 to TZ2 in stages or is it a rip and replace?

I currently have 3 NN3 MFD12s, with a DRS4 radar, a UFF1 Chiro sonar and a B275 transducer. I also have Sirius BBWX1. It’s all tied together with a Furuno Ethernet hub and is all 12V.

I have NMEA183 connections to a Simrad AP26 and also to my standard horizon helm radio. I have a pair of engine room camera going into the video inputs of one of the MFDs.

My hope is to update in stages as opposed to having to rip and replace which then brings in the Barmin, Ray Marine, Etc. Options.

Wat is an isn’t possible to get me from NN3 to TZ2 over 2 years to keep my budget happy?

You can keep the radar, sounder, hub and other items. They will all work on the TZT2. You can NOT have the NN3D MFDs on the same network at the TZT2. You would need to replace the MFDs at the same time or move the NN3Ds onto another network until you complete your upgrade. Only the TZT (not TZT2) can be on the same network as the NN3D.
