This is my first post, so would just like to say Hi to everyone Im a bit confused on fitting a new head unit for a 2006 Astra SXi. I have a Pioneer DEH-P85BT and was told that i need to get a Vauxhall Quadlock to Parrot ISO adaptor lead. I have now got this and have connected the stereo but it still wont start up, even with the ignition on..:S I have heard that on aftermarket headunits the red wire on the adaptor lead needs to be connected to an ignition switched 12 v supply in order for the HU to power up? Is this true? Just wondering if you guys had to do this and whether it was hard? Iv heard the supply that feeds the cigar lighter is an example..
Many Thanks for Reading this!
