8E0857925D - Genuine Audi Part Number. This came out of an Audi A4 that had the CD changer built into the glove compartment so was a very easily replacement for it. Simply un-clip your cd changer out and plug this in. It retails at £140+VAT at the Audi dealers. I have been told it may fit other models aswell as the CD changer is in the glove compartment (Pls confirm this yourself first). In mint condition and will accept any generation ipod as I have been told by Audi (Also confirm this with them)... The reason I am selling this is because I bought it not knowing that because I have an Audi Symphony with 6 disc changer, it cannot connect to this unit as it does not have separate unit in the glove compartment. ebay item no: 110907954128 contact no: Isaak 07826927833 less than half the price what this would cost from dealers!!!
