WinCE Hardware for navigation: "Serial Port Cable Information

For commercial solutions see below. This section covers general information for users want to build their own cables or adapt existing cables. Pocketpc devices generally come with both serial ports and USB ports but since gps units use the serial port this section will focus on serial port connections.

With any of the above solutions you will probably need a cable to connect up the two units. You can fabricate your own using a cable with the appropriate GPS connector on one end and wired directly to the pocketpc via a connector or if you prefer you can try one of the solutions described in some of the links below.

Another solution is to get a pocketpc hotsync cable and a standard computer interface cable for your gps. Then obtain a male to male gender changer null modem adapter connector to hook them together. (Fry's has these.) If you can't get a male to male gender/null modem changer in one unit then you buy a male to male connector and add a gender changer adapter but the overall link of cables and adapters starts to get a bit messy at this point. You can make your own male to male gender changer by obtaining two male 9 pin connectors. Then you would wire pin 2 to pin 3, pin 3 to pin 2 and pin 5 (gnd) to pin 5.

For pinout data check this source for the ipaq. Another source for Ipaq and Garmin gps pinouts is kh-gps.de. For Jornada and some others try Bev Howard's page."
