Good Morning,
The three photos are the components and cables on a boat I recently purchased. There is also a tiller auto helm connection that I didn't photo.
Can anyone tell from the photos the age or era or model of gps control unit compatible to get gps, depth and auto helm set up?

Thanks for any input.

 

It does look like that with the addition of the depth. It's compatible with a ton of screens. Is that connector a fairly universal plug for Garmin units?
