I have been reading that it is possible to use voice commands to control the SatNav and Phone.

I have an Australian model IS250 sports with the Enhancement pack and these features seem to be disabled.

The only voice command I can get working is the voice recognition dialing where you say the voice tag you have pre-recorded. when I hit the voice button on the SatNav screen, I get a message saying it is not enabled on this screen.

Does anyone know how / If this feature can be turned on?

Have you checked your owners manual to see whether voice recognition is supposed to be disabled while driving? Or called the toll-free Lexus help number to see if this behavior is intentional? Or for that matter, even asked at your dealer?

In the American market (one of the most litigious in the world), placing the car in motion has no effect on any voice recognition commands.
