c-map card needed

566 Views 1 Reply 2 Participants Last post by  shebeen
Hey everyone, I have a Standard Horizon CP160 GPS. My position where I actually am is off by a lot when in use and sometimes my speed says crazy readings. I called Standard Horizon told them the symptoms and they say my cmap card is bad, not the unit. Does anyone have a card I can borrow to see if this corrects it before I buy a new one? Thanks, Rich 631 404 5437

I have a c-map NT for southern Long Island that was used in an Interphase Chartmaster. I know they're programmed to the machine so I'm not sure if it would work in yours.

No use to me, you can have it if you want.
