Radar upgrade for NN3 - what radars are compatible?

[backman]

Which Furuno radars will work with an existing NN3 network and also with a TX2 network when I bite the bullet and upgrade?

That is currently sold?

DRS4D.

On the used market the following will work.

DRS4D, DRS4A, DRS6A, DRS12, DRS25A

So no stepwise migration forward from NN3 to TZT2, I have to do the Big Bang, rip out 3 MFDs, Radar, weather, fishfinder, network, etc and do it all at once....grrr.

Backman-
Are you saying you already have a DRS radar on a NN3D system and want to upgrade to TZT2?

 

[backman]

I have a DRS4 which is part of a 4 MFD NN3 network. I want to replace it with a 6K unit but don’t want to go buy a DRS 6a if it’s out of production.

I was hoping to upgrade either radar or the MFDs to TXT2 level in steps that leaves me with a full TZT2 network and components in 2 years but it doesn’t look like I can do it step at a time.
