Bluetooth Phone Operation

[swabby]

I have a 2006 SC430. I have used two cell phones with this car. The first one was a Blackberry Curve 8320 and the current phone is a Samsung Galaxy S Infuse.

In both cases the phones have been completely compatible with the car except that when someone calls me the phone does not ring through the car sound system.

The navigation system changes to show that there is an incoming call and fortunately I store the phone in the centre console so unless the top is down and the radio is turned up I can usually hear it but neither phone rang incoming calls through the car audio system even though the volume in the audio system automatically turned down.

Has anyone else had this experience or does anyone have any suggestions.

Thanks
