I just purchased a Garmin Street Pilot c330 street navigator. It rocks and is really accruate. As the summer is full on now I am wanting to pursue other activities more so on the water.

I enjoy scuba diving and I wanted to know if the navigator that I purchased can go to a specific GPS location. I am sure it is just a matter of software. Not sure if anyone else in here has used it? I do not think that it would be that much difference between the marine and street GPS units.
