I’ve gotten a copy of the build sheet for the 05, Z4, I have and it indicates that it is per wired for the 6 disc CD changer. My question is where/how do I locate the pre wired, wires. Tks. Pete
Hello Mr. Stresen-Reuter, the attachment has a picture with the location, it is the front left (driver’s side) corner of the trunk. If you are planning on adding or replacing the CD changer the car will have to be programmed in order for it to work. The dealer or a good independent shop will be able to do this. The CD changer is a computer and it essentially needs to be added to the network in order for it to work. Good luck, thank you for your question.
