Hi

I have a 2002 A4 1.8tq Canadian Car. What is the correct coding for stock Symphony II Bose?

I bought a used headunit and it is coded to 00201. I don't know which car it came from etc.

I already looked at Ross Tech wiki and that makes no sense. Almost as if what they have is for Symphony II+.

Can someone just check what they have and I'll replicate.

Thank you. Why is your 5th digit set to 5? What is that code for?

Nevermind. I think I answered my question. 5 is for diversity antenna with multi function wheel.
