I've been searching on ebay and the MFD2 DVD systems are out of my price range along with the MFD3. I could get the MFD2 CD sat nav system (part number 76120022 BNO 881 7L6035191F)
Are these worth it? its from a 2004 Touareg

I can't find a system with similar spec (Sat nav etc) for anywhere near the price

it will go in my 2007 Leon Cupra
