Hi,
Yes that's the problem of the TT driver. It prevents other App. to use
the Port. They replaced the original driver to fix a BUG on the iPAQ
2210 device. (If you have a Bluetooth connection and turn off the device
you can not turn it on anymore!)
Navigon the biggest competitor have also a fix for this BUG, but they
did it much better, there the Port is usable for all App.
Regards, Andrej
PS: You should try Navigon MobileNavigator in my opinion it's much
better then TT.
