To install the GPS adapter, you should grab the program files at the following URL:
http://www.nynaeve.net/Skywing/xv6800gps/gpsserver.zip
Currently, there's no CAB installer, so all of the installation must be done manually. Sorry. A CAB may come later on, if someone feels like doing the work to build one for me.
After extracting the zip onto your device, follow these instructions:
1. Create a "\Program Files\GPSServer" directory on your device.
2. Copy gpssrv.exe, oemgpsOne.dll, and stdgps.dll to "\Program Files\GPSServer".
3. Copy gpsapi.dll into the directory where your GPS program resides. For example, "\Program Files\GoogleMaps".
After that, you should be able to start your GPS program (e.g. Google Maps) and receive location data. Note that being inside in a shielded location may impede the process of acquiring a GPS fix. Also, to gain the benefit of assisted GPS mode, you need to have an active cell data connection, and you should not be connected to ActiveSync
