Possible to use Internal GPS in no coverage area?

[augie0041]

Obviously you cannot use Google Maps, etc in Europe as they require an internet connection to work. I am using TomTom so that shouldnt be the issue.
Also, I am aware that it should take some time to locate the satellites since I am in a much different location on the earth than the last time I tried to use the GPS. But I am expecting a few minutes, it has been a few hours with no luck.
I tried this both near the window in my hotel, and again in a cab and then kept it on as I walked through the town.
It simply isn't finding the GPS.
I need to select 'COM4' right? There are four choices in my Touch Pro, COM4; COM7; Virtual COM9; and RIL on COM6.
Any settings like this I should try from within TomTom?
