Possible to use Internal GPS in no coverage area?

[augie0041]

I am traveling to Europe this week and brought along my Touch Pro for the plane flights and using it as my PDA. I use TomTom all the time throughout the U.S. I installed the European maps but cannot obtain a GPS signal, am I doing something wrong?
Does the internal GPS require a Sprint signal?
When I used my PPC-6700, my bluetooth GPS dongle worked very well in Europe. I was expecting this to work as well.
