aux wiring into RNS-E

    Hello all,
    I have recently bought a 2010 A3 tdi Quattro s-line, after selling my beloved S4 v8
    certainly enjoying the increased fuel economy :)

    I have installed an RNS-E unit to replace the symphony unit, car has MFSW & aux socket in console, as well as Bluetooth.

    I was advised to move a brown wire from pin 5 to pin 7 in the blue plug of the quad connector.
    The pin 7 was already populated with a green wire , and according to the wiring on the symphony unit this was `aux R` input.
    `aux L` was another pin and also wired up.

    I have taped these up for the moment, and moved the brown wire from 5 to 7 as instructed.
    Anyone know where to wire the green & grey wires that are for the aux socket ?

    I won`t probably use it , but if its fitted it may as well be working.

    You need connector from audi, then remove B1, B3 and B7 and insert them in B1 > 22
    B3 > 21, B7 > 06

    thanks for reply,
    I presume you mean a new plug to fit in the long 32pin slot ?
    and then move the wires into this plug...?
