I am currently trying to figure out the same thing

. But anyhow that is correct that the treo 700wx is gps enabled, i'm not sure of what exactly that means, whether it means theres gps built in or if it means you can put gps accessory plugins and it'll read it? idont know. I think there's a few guides on youtube though on how to mess with the gps settings, like the COM ports and the Baud rates (under settings-->System-->GPS) And Windows Live Search, looks like under settings you can set which COM ports to use, but i dont know what COM ports will do anything? Try looking through youtube, theres a bunch of vids up of people showing how to go through things with the treo.
