"Wire iPod Interface on 2001 Vovlo S60 Radio"

2001 Vovlo S60

I’m trying to wire a USA Spec iPod interface into my 2001 Volvo S60 radio, the only thing I don’t know is which colour wire is the constant live?

Answer: Can’t tell you. But i can tell you to take the radio out and use a multimeter to determine it, when your keys is out of the ignition off coarse.
