I'm looking at a 40 foot Marine Trader that has a complete set of electronic displays on the flybridge; Radar, GPS, Depth sounder, Auto helm, and Stern thruster joy stick... It has none of this at the lower helm but a remote for the Stern thruster and a control for the auto helm. If I put a new GPS unit at the lower helm and link it to the units above with a NMEA 2000 cable, will it display the radar and depth from the flybridge at the lower helm?
