Yes, that is the GPS unit I have. All of the electronics are located in the antenna housing. You have two mounting screws and a small hole for the data cable. The power to the unit comes through two of those wires and is supplied by the E-system. Very convenient. Shop around on the internet. You can get it for less. I bought mine through someplace called “Marine Electronics…” Again, I need to look at my notes. In the end, the new GPS is a “slave” to the E-system, but there are worse things in the world. I recommend that you run the “high speed” bus to your Nav station so you can use your laptop and a charting program to develop routes and waypoints. Keying them directly into the E-System is a real PITA.
