"All of the VW audio techs I've talked to (from dealers to independants) have cautioned against any switch from the cars individual factory equipment."
The VW dealer from whom I purchased my Eos recommended the Pioneer AVIC F900B as they had fitted this model to a couple of Passats. I went for it & have had no problems with any of the programmes, nor the Ipod or Bluetooth systems. All work perfectly. I do not have a multi function steering wheel though so I don't know if that makes a difference. I wouldn't have thought so. Photo attached of Ipod screen.
