GPS is still "bleeding edge" technology and one area in which this is apparent is the lack of data cables for the Macintosh. Except for the latest units which have USB connections, many data cables provided by GPS vendors are "unterminated" (meaning raw data cable strands); or terminated in a PC style DB-9 connector.

In general, we recommend that you purchase the standard PC data cable for your GPS unit from your dealer; and use it with the Keyspan USB GPS Adaptor (below). This gives you the most flexibility in the long run as you can switch GPS vendors or use a PC power+data cable in conjunction with the adaptor.

For USB-only Macs, see our FAQ on GPS/USB connectivity. You'll need a serial to USB converter or a serial PCI board to hook up your GPS unit. We recommend the Keyspan USB PDA Adaptor (see below) in conjunction with the standard PC data cable sold by your GPS vendor or our eTrex/eMap data cable.

Global Mapping Systems offers four types of GPS data cable adaptors:

Item	Price	Description
Keyspan USB Serial (GPS) Adaptor	Available from Amazon.com: Keyspan High Speed USB Serial Adapter ( USA-19HS )	Designed for use with Macs that only have USB ports Works with our eTrex cable for Garmin eTrex/eMap Series GPS. Fits most PC-style (female DB-9) GPS data cables including those for Ashtec, DeLorme, Eagle, Garmin, Lowrance, Magellan, Trimble and other GPS manufacturers This cable mates with Garmin, Eagle/Lowrance, and Magellan's "PC Interface Cable" or "PC Interface Cable with Cigarette Lighter Adapter" for their series of GPS units.

Generic PC DB-9 Male to Macintosh Mini Din-8 Male Adaptor [Click to enlarge]	Currently unavailable	Fits most PC-style (female DB-9) GPS data cables including those for Ashtec, DeLorme, Eagle, Garmin, Lowrance, Magellan, Trimble and other GPS manufacturers This cable mates with Garmin, Eagle/Lowrance, and Magellan's "PC Interface Cable" or "PC Interface Cable with Cigarette Lighter Adapter" for their series of GPS units. Works with our eTrex cable for Garmin eTrex/eMap series Is the best solution if you wish to use a manufacturer's Data/Power cable with your GPS to supply power (cigarette lighter/etc.) while using your unit with GPSy. Purchase the manufacturer's PC Data/Power cable from your GPS reseller (verifying it has a standard PC female DB-9 connector) and then use this Generic PC-to-Mac data cable adaptor to convert it to the Mac's Mini-Din8. Please note that while there are many cables that look the same as this cable, they usually will not work due to wiring differences. We are not currently aware of any off-the shelf cable that works without modification. The Palm Adaptor is the closest, but you still need to modify it. Most off-the shelf will simply not work otherwise we wouldn't be selling this. Note: requires the manufacturer's GPS data cable for PCs to interconnect with your GPS unit Bundle Price: Purchase the Generic PC-to-Mac Cable, GPSy CD-ROM, and GPSy together for only $75 with 2-day shipping (normally $100; save $25).

Please note: cables come with a limited 60-day warrantee and money back guarrantee (sans shipping+handling). All cables are fully tested before being shipped. Please verify which cable you want (and whether you want a cable or not) as after placing an order; you will have to pay the shipping/handling fee for any cancellations or substitutions. Garmin data cables are data only and are sealed during construction for strain resistance. Data cables are non-user-serviceable, dismantling a cable will undoubtedly destroy it.
