Hi all, recently bought my grande punto dynamic 2006 and decided to fit an aftermarket headunit. Bought the Pioneer DEH-2600UI and popped out the standard HU (a blaupunkt I believe) and connected the ISO to my new HU, all fitted perfectly albeit a new cage is needed as it doesn't fit. Basically the issue is there is no power to the HU; it won't turn on regardless of whether the cars electrics are on or not. Can anyone shed any light on the situation? I can't find a solid answer anywhere
