Hello All,

Wondering if anyone can shine some light on what Pin No.2 on the Black power connector does on the Concert 2 stereo. The Pinout diagram has it listed as "DWA-GND" and I wondered what this was?

The reason I ask is because my A2 has a Concert 1 installed, now been a 2002 model I was informed that this was the wrong head unit for the car and that a Concert 2 would be more suited because it has the CAN BUS interface built in.

Now Pin No.2 on the Concert 1 black power connector is listed on the Pinout diagram as "Tel Mute" when turning on the Concert 1 for the first time after buying the car all is displayed was 'Telefon' to correct this I cut the brown cable feeding Pin No. 2 on the black power connector and all was OK.

Now I am looking at installing a Concert 2 I wondered if that connection will need to be made again or if it will be OK running without the connection to DWA-GND?

Many Thanks.
