see my link in my sig for the RNS-E for C5 A6 folks....and also read through the details via quicklinks:
1) 2004 allroad won't be prewired for CD changer in trunk; you've probably found some prewiring for the OEM SAT tuner. Can you describe the cables that you've found (round, square, etc..etc)? FYI - the phatbox will connect in the trunk the same way that the OEM trunc CD changer will.
2) you will need to buy the CDC cable and run it from behind your Sym II to the trunk.
3) If you want to run SAT and CD changer(or phatbox) in the trunk and control both via the RNS-E at the same time...you will need to make a custom cable to utilized the audio pass-through on the SAT tuner.
4) if you don't want to use SAT radio, then you will need to move some pins around at the head unit to do this.
Also, you might want to make sure you order your plug/play RNS-E connector WITH the wiring for CD Changer.
Again see the links in quicklinks for more details.
Happy reading!
