Sorry to bring this up again but I havn't found a solution yet. I have installed the Aux input plug into the back of the head unit (Boost CD + HK) on my MCSC. 'AUX' comes up on the display when I press the mode button twice. I press the note key and can adjust the bass, treble, balance, fade etc. I press and hold down the note key and can adjust TP, PTY etc. Nowhere can I find 'Aux vol'. The handbook is no help.
I plugged the lead into the spare socket at the left bottom of the unit (looking from the display) is this the correct one or is there another spare one that I have missed. Hoping someone can help. Many thanks.
