[C320-list] How to get Raymarine Auto Helm to talk to a Garmin Chartplotter

[Charles Martin]

Has anyone tried to connect the standard Raymarine Auto Helm (uses SeaTalk
comm) that was factory installed in C320's to communicate with a Garmin
Chartplotter?  If so, did you use some sort of cross-talk adapter?

Best,
