The Garmin StreetPilot C330 GPS device comes preloaded with maps of North America. As time goes on, cities and towns change and expand and new places are founded, creating the need for new maps. To provide the most accurate directions, Garmin provides updated maps that reflect these changes to its customers. The updated maps can be downloaded from the Garmin website and transferred to a Garmin GPS device using the company's proprietary software.

Download Map Updates

Connect the StreetPilot C330 GPS to the computer using the USB cable. Insert the smaller end of the USB cable into the GPS, and insert the larger end into the computer's USB port.

Step 2

Go to Garmin, and select "myGarmin" from the upper-navigation bar. Sign in or register for a Garmin account. If registering for an account, complete the registration details, then select the "Register" option on your Garmin account page. The site will detect the connected device and register it.
