After recently buying this GPS system, I wanted to list all the hints, hacks, and tips that I have found for it.

The StreetPilot c320 and c330 systems are very similiar. c320 is a little cheaper and uses SD cards. c330 uses internal flash memory. Anyway, these units rock, have a ton of features, are frequently updated, and are pretty cheap now.

Props goes out to gpspassion forums for many of these tips.

c320/c330 Hints:

Software Updates:

The system comes with a map of CDs and some basic transfer software. Seeing and setting your points of interests and waypoints on your computer is made much easier by downloading and using Garmin's free MapSource software.

If you want to connect your notebook to your GPS system while you travel to get killer information, stats, and better view, you can download and run Garmin's free nRoute software.

You are probably entitled to at least one free map update as well.

Access the Debug/Diagnostic Pages:
1. Turn GPS on
2. Click View Map
