Got it. I think I have led you a bit astray of my goals, so please let me back up for a moment. I need to replace my C80 MFD because the NMEA0183 port is damaged (confirmed by wraparound test) and I am not able to get position data to my VHF for DSC utilization. That is a safety issue that I need to address. The eS97 has a nice drop-in size for my existing helm space and I am trying to upgrade without having to re-fiberglass and gel coat the entire helm.
The ST290 is causing problems because it has a huge cutout. None of the replacements (i50/i70) are large enough to fill that [censored]. I only use my ST290 for speed and sea temp data--that is it. So I really don't need to replace it. What if I keep that as an isolated SeaTalk2 system and upgrade in two steps as shown in my diagrams?
Step 1 is adding the eS97 MFD and the STng backbone.
Step 2 is replacing my existing autopilot with an Evolution system.
Q: With the eS97 having a built-in GPS receiver, should I keep my existing RS130 GPS receiver so I have two GPS sources? Or get rid of it?
Thanks
Dave
