Ok, I know this has been asked a million times, but there are a lot of different answers, and its quite confusing.
I have a 2005 Astra H, pre facelift, with a blaupunkt CD30MP3 (the one with the 6 buttons). Does this, or does this not, have the ability to add AUX In? As seen on the cd30mp3.co.uk site, when I press the tuner/fm/am button, it does nothing but change between fm/am, and does not display an AUX option. Does this definitively mean that it does not have the ability, or could it simply be deactivated with tech2? Would the best way be to pull the stereo out and have a look? Will it have AUX IN on the wiring diagram, or will it be under something else?
It also has a 'BC' button, that when pressed says 'no function'... what exactly is this?
