Garmin's upper end Chartplotters. Available from 7 to 12 inch screen. These units have the essential connections needed to connect one device type per graph. Unlike their 10x2/12x2 counterparts, these are all touch screen, no keyed assist. They do have much better screen resolution than the 10x2/12x2
XSV - Means direct sonar capability, 2D, Side imaging, Down Imaging
Non-XSV means you need to have another graph for sonar, you can network this over
NonXSV models WILL display livescope data since it uses ethernet to communicate.
These will not communicate with Echomap units (93SV/106SV/126SV etc)
