I recently changed a 2002 Punto for a 2004 Punto. My query here concerns the
(re)installation of my audio player.
I had a Sony CDX-MP30 in the 02 and expected a simple swap over using same
ISO harness in the 04 that I had in the 02. However, when I fitted the Sony
into the 04 I got no response at all - no power to the unit.
Is there a different wiring config in the newest Puntos? And, if so, can
anyone help me with reconfiguring the wiring? I
know very little about car audio systems but I'm assuming (hoping) it would
be a simple matter of changing the "slots" around on the harness.
My hope of simply matching up wire colours was a non-starter as the Punto's
wiring has a completely different set of colours to the harness. Also, the
04 Punto has one wire extra compared to the harness - although I don't
know/remember if this was the case on the 02 Punto.
