I'm about to install a suite of Garmin electronics
which is something I've never done before. For me, pulling the different cables
are the easy part. It's the interconnectivity of the different devices I'm uncertain about. I've put together the attached diagram showing what I thinks needs to be accomplished to get them to talk to each other. Would someone more knowledgeable than I validate my drawing. Are there any red flags
or anything I missed?
If I decide to contract
it out, what would be a reasonable cost?
