Setting up Topo USA
Here’s the easy way to set up Earthmate PN-20 GPS straight out of the box so you can plan your first route in the great outdoors and let the PN-20 be your virtual guide once you get there. First off, get your SD card and batteries ready. Then unscrew the D rings on the back to remove the battery cover. Pull the ribbon under the cover to the side, push the latch on the bottom, and insert the SD card with the label side up. Then place the batteries in according to the diagram. Replace and tighten the cover.
The TOPO USA software which comes out of the box with this DeLorme offering is where you do the setting up and transferring of data from your computer to the unit via the USB cable. You have the option of transferring the data you want directly into the 75 MB of internal memory or onto an SD card which stores 2 GB. Having an SD card enhances the unit’s performance when using large maps which is why these instructions include installing one in the process. Having the Quick Start guide, which comes with the box handy is helpful throughout the process. Incidentally, to find out more details about the differences in capabilities, features, and pricing within the PN Series, read this article on the Top Three DeLorme GPS Model Reviews.
Place the Topo USA Install CD in your computer. The installation wizard walks you through the process and make sure you complete registration information about your unit because that info is necessary for acquiring data including aerial imagery. Once the installation is complete, replace the Install DVD with the Data DVD which you'll need for working with Topo USA. Aerial Data Packets (ADPs) can be downloaded online and usually you get a free download certificate out of the box depending upon what packet you choose.
