    What you have there is a Smartcraft System Monitor. It is really old technology and has ZERO functionality with your Lowrance. You need to replace it with a Level 1 or 2 Mercmonitor. Those have NMEA2000 functionality and can share data with your HDSs. You will also need to install a NMEA2000 network if you do not already have one.

    Thanks. The boat is a 2017 Phoenix and has the nema network. Do you have any idea on the price of a Mercmonitor?

    If you're saying that monitor is on the NMEA circuit, then all you need is NMEA cable for Lowrance and a T connector to install on the existing NMEA.

    The PICTURED System Monitor has absolutely no means of being connected to a NMEA-2000 Network. Some other gateway device is required.

    If you email Rhonda in our Parts Department (see her post that's Stickied at the top of the forum), she can assist you with exactly what you will need.
