I cant believe the steering wheel remote for the Z is almost half the freggin' price of the one for the D... Anyways, since the Z has voice recognition, is it really worth the $30?? http://cgi.ebay.com/NEW-PIONEER-CDSR1-CD-SR1-STEERING-WHEEL-REMOTE-W-VOICE_W0QQitemZ9725704765QQcategoryZ94852QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

I guess its worth it if you don't like bending slightly to touch the voice icon on the screen,and also it should have the bluetooth phone button.

Personally, I love having the volume controls at my fingertips... while it is not a tremendous leap of physical ability to reach over and touch the volume buttons, its certainly a convenience Ive now become quite used to!

It is, apparently, if you want to mute the volume.
