iGO8 also works for me with no need for configuration.
It does need to be set to 'Use Device Settings' for orientation, and if set that way will start up in whichever orientation the device is in when started. Changing orientation give an odd split screen effect, as does using a set orientation with the settings. Hopefully someone will device a proper sys.txt file for the TG01 soon!
I also found that I need to define a Custom setting in the device's Power Settings- the Best Performance setting uses automatic screen brightness which is too dim for in-car use, so I've got the Custom Setting set with everything turned up full! Not checked to see if these can be modified in the registry, or if others can be added via registry entries.
