Here's what I did when I was in the states...

1. Start TT7 normally and wait about 5 seconds to get a lock (keep phone/data ON at this point)
2. Press the END key to minimize TT7
3. Go to your comm manager and turn ON bluetooth, and turn OFF all other connections (i.e. phone/data)
4. Go back to TT7 and it will run great without data connection.

Few things to remember: TT7 doesnt work in flight mode so you must keep at least one connection active (thats why I keep the bluetooth active), TT7 doesnt require data but the Vouge takes really long... like up to 10 minutes to find a lock without using the "assisted"gps (which uses phone/data connection).... this is why I let TT7 use aGPS for the first 5 seconds to get an initial lock and then I turn off the phone/data and the inhouse GPS works just great afterwards... I dont even think you'll be charged for data and if so it will be very minimal... hope this helps!
