I thought I would introduce myself as a new member who needs help from all the experienced members. I have just bought a 2006 December reg 318i SE and love it. I'd like to fit a CD changer. I bought a 65 12 6 964 602 unit from ebay but my local BMW dealer said it was the wrong part number. The ones I need are 65 129133076 or 65 129143439. I don't want to go back to Ebay or the local stealer. so how else can I source one.
