What does the GPS receiver do that the other does not do?

[Williamhawk]

Hello everyone,

I am looking for a GPS navigation system. I found the Garmin StreetPilot C330, which looks like a good match for me. I also found the Garmin StreetPilot C330-GPS receiver. What is the difference? What does the GPS receiver do that the other does not do?

Any idea, suggestions would be appreciated,

Thanks,
