My 2013 Pioneer head unit leaves the antenna up if I'm listening to an iPod or Bluetooth source. Was a little disappointed at that. Haven't actually tried the CD player yet. My <aftermarket> power antenna quit working (stuck up) a few weeks ago. Its the ONLY thing to break so far this year with 4 months of daily driving. And by all logical means, it SHOULD lower it when not in use. It has two auxiliary switched outputs. One labeled for antenna (only on with tuner), and one for an amplifier (on with head unit).
