I just picked up a used 998 and have a question on the GPS module...can I connect it directly into the back of the graph or do I need to hook it into the NEMA cable...does the antenna take its power directly from the graph or do I need a seperate 12v source...seperate from the power source for the graph head.

Connect the GPS antenna directly to the back of the unit in the matching connection that is shaped like a rectangle with the top right corner of the rectangle slanted ...
The GPS antenna is powered by the head unit ...
