2007 RS4, trying to fit aftermarket gps head unit

[Paddys Parts]

Hi Guys,
I hope I'm posting in the correct area and that I'm following site rules as I'm new here so please forgive me if I'm not.

I bought an aftermarket replica Audi Unit with Sat Nav and Dvd player on ebay for my 2007 RS4 as it just had the standard Audi Symphony radio, its says its Symphony B7 Soul, I also have Bose speakers in the car as well.
However when I plugged out the plug at the back of my radio and plugged in the new unit i had no sound, it was meant to be a simple plug and play unit but this is not the case, the seller is refusing to take back the item and I can understand that, I did try plugging it into a mates Passat and it worked perfectly as the plug is the same but I cant get sound in the Audi, I will add pictures of the wiring harness and perhaps someone could advise me what to do or if this is possible, perhaps there is a harness that will work somewhere, thanks in advance,

also as you can see from the pictures, the third picture is of the audi wiring harness and the fifth picture is of the new radio harness.

Get a MK2 RNSE imo , you won't be disappointed and it will fit in no problems at all.
