Hi all I would like to update my gps and plotter! Currently I have a Garmin gpsmap 232 and a Koden echo sounder running off a 1kw Airmar transducer. I dont really fish out wide and deep more crayfishing and trolling. I was thinking of one device rather than two like I have now. Also would like to transfer my waypoints from my data card.

Any advice would be greatly appreciated.
