But have wasted so much time on trying to get Samsung Omnia II to hook up to GPS today...
Whatever you do, don't change the default settings:
Go to setting --> General Setting --> GPS --> Connection
GPS program port: com7
GPS hardware port:com9
Baud rate: 4800
Click on done.
Go to XTRA
Enable XTRA Server
Tick "ZWhen connected to PC via ActiveSync
Enable SNTP Server (Only when you have data plan)
These settings work!
