mate of mines just swapped his stereo & cd player & gave me the standard head unit & 6 cd changer from his Cordoba SX. Trouble is he'd not had the car long & when he bought it, he wasn't given the stereo code. I've tried both in my car & cd changer works fine. The stereo lights up but just says 'safe' (I'm assuming it needs decoding - does anyone know how I go about this - I imagine taking it to a dealers they'll charge me for it. Can I source something off tinternet for free? Mine's already got the same equipment so I'll be flogging both soon - how much do you reckon I'd get for them?
