I am new to the boating world... and let me tell you.... I love it and can't wait to get the boat on the water this year! One of my friends told me that I better not even attempt to go out on the water without a GPS/Navigation... Does anyone have any suggestions or recommendations on a good one?? I was looking on-line and the only ones I have been finding have been $700 and up... and I just can't spend that much $$ on it right now! Anyone have any ideas on where I can find something cheaper and what I really need?? Any help or suggestions is so much appreciated!!!!
