I’m using the 4 inch screen for the processor and adding a larger mfd. I have to redo the dash but I’m still an analog gauge lover, so they are staying.

I found the 403 new in the box on eBay for $750. And it fills the hole of the current unit for the mean time and allows me to start my NEMA network. My thoughts are the 403 will eventually end up on the passenger side in place of the gps Speedo and the larger mfd at the helm. However I still need to map all this out and have innotech cut a new dash panel

the 403 is worlds over my monochrome vessel view.

Limited real estate on a nor-tech. That is a garmin 3206 on the bottom left. The panel over the wheel is only 12 inches top to bottom
