Nov 29, 2023 · Hello, well, I have purchased a 2 DIN Blaupunkt Audi Concert Radio, which comes with the Audi A4 B7. I want to connect the radio to a source to check the Pin Code, but I am not able to, or the radio does not work. According to what I've seen Terminal 12 = Ground Terminal 13 = 12V Terminal 15 = 12V. I did this, and it doesn't turn on.
