Keep CD Changer AND add RaspControl?

[Baddabing]

in aux mode with correct setting, pi gets enabled (control with rotary encoder and ntsc or gpio7 active).

Thank you again Harry.

Hope we can take this slowly?

'Correct setting' in which software please?

And when you say 'ntsc or GPIO7 active' - what do you mean please?  [I have TV module upgraded with PiBusTV PAL].  I would prefer to use Hifiberry DAC for sound - which would use GPIO.
