I have two garmin echo map 70s chartplotter/2d touchscreen fishfinders for sale along with the gcv 10 which will network to both via ethernet and enable sidevu and downvu. The units were all bought spring of 2015 and saw the water less than 5 times. They are also panoptix compatible if you choose to purchase the transducer. I have all cables, mounts and one 2d transducer for the bow and the sidevu transducer for the transom. Asking $1500 for all, will not split up. You can not find these units any more. Thanks for looking.
