Audi Symphony 2 Cheap Easy Bluetooth Conversion. Step-by-Step Guide to VCDS Programming and Wiring

Despite being a relatively old audio unit, the Symphony 2 is a fine piece of equipment and with some VCDS programming and a few modifications and simple hardware it can reproduce Bluetooth audio. This video shows the step-by-step process to accomplish this task very cheaply and with professional results.

The Bluetooth adapter from ali express works fine. Plug man right in 7$ plus 4$ ship. You still have to change the coding. It’s the adapter with the white plug…

good morning/good afternoon friend. Do you know where I can get the instruction manual for this radio?

Do you need to buy an official cable to have this work? Ive had no success with the cheap ones on ebay. Which cable did you use?

Hi I got an Audi a3 8P and I’ve bought a Bluetooth called tarissa Bluetooth adapter to the car, it was meant to play on the cd option as well but since my radio doesn’t have the option to have more then one CD on the car he keeps saying no CD and it is suppose to appear on the screen CD1 / CD2 some people say I just need to code the part of cd as well on the same program as u used can u help me in anyway? Cause they say car needs to recognise that CD is meant to be Bluetooth or something like that mt radio type is the Audi Concert 1

You should code the unit to accept the AUX input as shown in the video but you will need to do the wiring of the BT receiver too. These units are not BT-enabled from factory so you need to adapt it as shown.

Do you connect to your car with an OBD cable or directly to the radio?

[@bettervisually902]

You connect to the radio via the OBD port in the car.

Hello im trying to add Bluetooth to my ipod in the glove box, but it shows no cdc and it has no power any suggestions?

[@bettervisually902]

Hi there. It might be that your radio is not configured to support a CDC (CD Changer) and therefore cannot accept an external audio signal in that port. You need to research the options of your radio and enable the CDC if possible.

I have the same iPod adapter in my glove box with the Symphony 2+ . I tried a Bluetooth adapter for the iPod but I would have to turn the key off and on to get it to work then it would stop playing. I took out the iPod adapter and unplugged the blue connection on the back of the stereo. I changed the coding to external source then ordered a Bluetooth adapter from Ali express. The white plug goes in where the blue came out. Hooked up a power source to the white wire on top. You want a power source only when the key is on. It work fine and is a cleaner installation. There are no wires visible.
