I've got an 898 up front on my trition on a ram mount and one beside my dash. If i get the interlink and an extra 2 inch ball and power cord, can i hook the interlink to the rear gps antenna and hook the other 898 up to it behind the dash mounted 898 so i can run one on maps and other on side imaging and mark points while having full screen map. Then unhook it and move it back to the front, but i want it to use its on gps antenna on the front.
