standard stereo's and disc changer fitting help please

[rickmyster]

I have a 05 lcr with the standard aura single cd head unit i am wanting to fit a standard seat disc changer aswell. basically is there a lead for the disc changer already presnt in the car coming from the head unit or do you have to purchase one from the dealers?

you need to buy the lead

My dealer mentioned in passing that the Aura head unit is essentially a Sony underneath. Is the lead therefore the same as Sony/Alpine changers, and are they compatible? I think what Seat charge for them is ludicrous.
