We do nave a cable to run one GPS receiver for 2 units. The part number is AS SYSLINK, but if I was goingto spend the money I would suggest what ShilohRed is pertaining to. It is a box that you install under the dash with 2 cables. The console unit will fit in port 1 and the bow unit will fit in port 2 and the GPS antenna will fit in the other slot. Pretty easy to install. This will allow you to create a waypoint on the console and it will automatically transfer the waypoint to the Interlink box and the unit on the bow and will do the same thing on the bow.
