Garmin 721
 

Hello brothers and sisters!
So! Christmas is coming and I'm thinking about to upgrade my chart plotter on 'Alianna". I have and old , 5 inch Garmin and want to replace it with the Garmin 721, touch screen. My concern is if the old cable would be compatible with the new chart plotter? Any opinions on the 721 model, do any of you own one. Any feed back highly appreciated .
