I just bought a 2004 E60 2500d and I would like to know if the system also reads DVDs or only CDs. The car came with a Navigation DVD for Europe but when I put it in the CD Player it doesn't read... Who can help me with this? Thanks

If your vehicle is equipped with Navigation, there will be a separate DVD drive below the primary CD drive. If you have only one disc slot, then you don't have Navi.
