Parrot Multican installation on Audi A3
Installation notes
The below are notes an suggested changes to the installation instructions that come with the Parrot Multican with CK3000 installation on Audi A3 vehicles with the Concert Radio.
Most of the information in the Multican installation manual is correct, the system is pre-wired with audio in/out connectors and power in/out connections that allow for mostly plug-in installation, however, they do not provide a connector set for the can bus interface cables and the mute they provide is not the correct one for phone operation.
Can bus connection:
The can bus connection needs to me made to the vehicle harness to the 20 pin connector on the rear of the concert radio, the pins are shown in the diagram below, you will need to carefully peel back the harness protection sheath to expose the wires, the can bus wires are:
pin 7 which is the can High wire that connects to the green wire from the Multican kit
Pin 12 which is the can Low wire that connects to the white wire from the multican kit.
See Fig 1 for radio connector rear view
Fig 2 shows a detail of this connector.
Note: The can wires are for an on board network, these connections are important as they deal with control of all confort and entertainment functions such as the data dieplayed in the dash display, streering wheel control, etc. Because of this it is imperative this be a solid connection, I would not suggest using quick splice connectors such as Scotch Lock connectors, I suggest making a solder connection covered with heat shrink or at least a solid crimp on connection to be sure these connections last.
Mute connection:
The kit has 3 mute wires available in the harness, the yellow and white work but they only serve to lower volume and do not make the radio go into phone mode. The connection that should be used is Pin 1 in the vertical connector to the left of the others Pin 1 is the bottom left pin of this connector as in the picture above, it is not used unless there is a phone kit already in the car, you will need a very small spade connector to slide on to this pin, connect to the yellow mute wire from the multican kit, the wire that comes from he multican box and not from the radio connectors. Fig 1 and 3 show the pin for this connection
Fig 1 Radio connector rear view, note the can bus connections and mute imput. The multican harness does not have these connections available, they all have to be made manually.
Fig 2 Can bus connections. Detailed view: these are the pins you are connecting to, see notes above.
Fig 3 Phone Mute connection, do not use the mute imputs in the parrot harness, these only lower volume and do not put the raido and dash display into phone mode. You will need a mini spade connector crimped down to fit onto this pin, be careful not to short to other pins.
