After updating to iOS7 on my Apple device, the MENU, UP, DOWN, and ENTER buttons do not work on the unit and/or remote.
The MENU, UP, DOWN, and ENTER button on the main unit and/or on the supplied remote control will only work with Apple® devices running iOS®6.
To operate your Sony® device with an Apple device with iOS®7 installed, please use the screen on your Apple device.
NOTE: Depending on your model, you may still be able to use the remote for these functions.
