Just bought a 2003 C70 and I've replaced the standard Volvo unit with a Pioneer double din unit.
I've got the connection kits with the RCA to DIN plug - Cut a long story short, everything looks to function perfectly, however there's no sound - I'm fairly convinced I need to connect the little blue wire to something in order to tell the on-board amplifier to turn on.
Can anyone tell me where this needs to connect to please, or indeed something else I'm missing.
Thank You
