Here's an older, but completely functional chartplotter. Includes instruction manual and CMap cartridges for Puget Sound to Cracroft Island and Strait of Georgia. Asking $40.
The unit is as shown in the pictures. It has the OE power/data cord that has a proprietary plug-in connector on the back of the unit. The other end of the cord just has bare wires.
The display is monochrome, not color.
I do not have the Standard Horizon antenna with coax cable and connector but I note that they seem to be readily available on Ebay.
It also has the original manual and dust cover (cover has some cracks in it)
