14 Part I — Hardware Hacks No cable connection also means that you cannot update the firmware on the GPS, and thereby take advantage of bug fixes and new features released by the manufacturer. How you acquire the cables is up to you. Shortly I will take you through the process of making them and you can also save yourself time (but not money unfortunately) by making these for yourself. The overwhelming advantage of making your own cables is that it offers you some practice with figuring out the wiring before progressing to more complex “multi” cables. Let’s take a brief tour of the different types of cable. The <strong>Data</strong> Cable A data cable is pretty self-explanatory — it is a cable that is used to transfer data between a GPS unit and another device. That other device is usually a PC or some form of handheld mobile device (such as a Pocket PC device like the HP iPAQ). When connecting to a PC, the port to which the cable connects is the serial port. The connector used is usually a 9-pin D connector. Figure 2-1 shows a PC-to-Garmin eTrex data cable.
