My unit will power up but will not locate a satellite. It is "brand new", it sat in the box with batteries for 3 years before I got it. I contacted Garmin and they said to send it in for repair for $59.00. <br />My question is; is it worth it? I don't need anything too fancy, just the basics. Should I fix the gps12 or should I think about getting a gps72 or a gps76?
