Garmin makes a great series of affordable GPS receivers, but though they can be connected to your computer or powered from an external source, finding or making a cable can be a rather difficult undertaking, as they use a custom connector not found anywhere else. Garmin does sell several cables to use with their units, however, they are quite expensive (and there is a noted lack of support for the Macintosh!) In an attempt to come up with a cost-effective solution to connect a GPS 38 to a Macintosh, we stumbled across Purple Open Projects (POP) at pfranc.com. They have created "sharehardware" variations for three of Garmin's custom GPS connectors, with a unique method of obtaining one:
As mentioned, three different styles of connectors are available. The large round connector works for most of the popular original Garmin GPS models requiring a round plug with 4 pins (with or without a 5th centre plastic post). The rectangular connector supports the eTrex and eMap receivers, and the smaller round plug works with the Rino receivers.
Also, prebuilt cables are now available for those of you who would rather not construct a cable yourself. Data cables are ready to be used to connect your Garmin GPS receiver to your IBM compatible computer (or any other device that uses a DB9 serial connection). As well, a power inserter cable can be used in conjunction with the appropriate data cable to provide both power and data capabilities to most receivers. For those using an eMap or eTrex, if you prefer, you can obtain a combination data/power cable that already has both capabilities built in.
