I have an 1198 Bird with the GPS puck located directly above my transducer which is mounted on the back of the boat. I have my I-pilot/link of course on the front. When I'm moving along and I find brush I would like to fish, I mark it on my bird. When I pull that mark up on my bird and hit "GOTO" the I-pilot takes me to the spot. The ? is, does it use the puck at the back of boat or the GPS inside the I-pilot?

Thanks, Shakynerves
