I've got a Blitzsafe Aux-in adapter for a Symphony II headunit.

I used it in my 2001 Audi Allroad to play my Apple iPod into the CD Changer inputs

Paid $80 -- Asking $50
US Shipping included

Will it work on a '00 A4? I assume it will. It has the cd changer assembly in the trunk, without the changer. I'll give you $40 for it. I've seen them for $50 brand new, but not a Blitzsafe. Do you have paypal? my email address is vitonxl@yahoo.com. I was going to buy one last weekend, but been busy.
