What does network share?

[noahtn]

I’m new to Hummird so looking for some answers. I have G2n Helix 10’s. An SI at console and DI at Bow. They are networked. I have a DI transducer on the trolling motor and a Mega SI transducer on the transom. My questions are below.

I have a Lakemaster card at console. Does the unit at the bow share that card’s map or does it need its own map?

will it DI at the bow show mega DI from the transom transducer? The transducer on the Trolling motor isn’t mega, but wondered if it would show Mega if it was reading rear transducer.

Helix does not share Map cards, and can not separate GPS from heading sensor when using a GPS/HS external puck. Everything else can be shared
