Fcv800 color matching NMEA 0183 to GP1871

So I have my GP1871f connected to my FCV800 via NMEA0183. And I think I did it correct. Blue wire TD to blue RD white wire TD to white RD. (Or is my wiring wrong ? When I push the Mark key is keeps saying no position data. Does anyone know what color wires go to what color?
 
This is how I hooked mine up.FCV588 is the same wiring as FCV800.Also you need to press the mark button twice on the sounder for it to show up on the gps.
