Does anyone know for sure if the 450h, with the newer Nav, will allow voice destination input?
Does it have voice dialing for the bluetooth phone?
Does the ML audio system allow you to play mp3 formatted cd's.
Does it have any aux audio input?

Just asking since this is available now on the ES350 and I think it is the same system.

Thanks

 

Yes

The head unit has logos for both WMA and MP3, so I assume support for these has been added.

No. There's no aux input.

 

The above is correct and also there is voice dialing via bluetooth connection. You can dial by name or number via voice command, while the car is moving. To do it by name you must first set up a voice tag for each person you may wish to dial by name using voice commands. It sets up pretty easy once you find the menus to do this.
