Can anyone comment on if the Voice Control command on the iPhone (or touch) can control the iPod player while the player is connected via USB?

I can get the voice control to work when I'm streaming Bluetooth (i.e. "Play artist Madonna", but can't seem to get it to work when I have the player hooked up via USB.

I'd rather use the USB connection, since the onscreen display shows song information (title, artist, album) this way than it does when you are streaming with BT.

It's so much faster trying to find particular music using the iPhone's voice control functionality than scrolling through lists (ever sooooo slowly) using the Lexus' iPod interface.

(I have a 2010 HS 250h).
