Topic: Software upgrade

[BrockSolid]

I plan to upgrade Helix units. Going to buy a new 10 or 12 G4N for the bow and a 9 for the console.
My question is, if I bought a used G3N for one of them, are there any issues or problems with networking them after the software upgrade?
Obviously I would like to save some $ if possible.

Thanks

HELIX G3N and G4N will share everything except mapping data  ... you would need 2 mapping cards if you want more than the basemap in one unit  ...
