I've used a number of different bt gps units successfully with the Omnia. My only gripe is they only allow two ports for this so I occasionally have to delete a profile to use something else. You don't necessarily have to do the registry hack to get the external gps icon as most software will connect without changing any of the settings it will reveal. You may however want to install one of the many "GPSInfo" type of apps (generally supplied or available from the h/w vendor) that allow for troubleshooting.
