Volkswagen Passat owners may find the need to remove their vehicle's factory stereo for various reasons. Connecting an external stereo component, repairing the unit or replacing the CD player are all things that require you to first extract the stock deck from the Passat's dashboard stereo dock. Whatever your reason for removing the CD player, the job is fairly straightforward, so save yourself some money and do it yourself.
Open the bonnet to access the Passat's battery. Loosen the bolt that holds the negative battery cable clamp around the negative battery lead post. Lift the cable from the battery terminal and set it aside, away from the battery leads. Return to the inside of the car.
Place each of the four DIN removal keys into the slots at the corners of the CD player. Each key has a plastic-coated ring at one end and a triangle-shaped metal point at the other. Slide the keys into the slits so that the flat edge of the tips is facing out, with the slanted side of the key facing in.
Push each key into the opening until it clicks into place. Feed a string (such as a shoestring) through the two rings of the DIN removal keys on the left side of the CD player. Feed a second string through the rings at the ends of the keys on the right side.
Pull both strings, sliding the stereo unit from the stereo mounting dock in the Passat's dash. Grab the stereo once you've pulled it out far enough to grip it by hand. Pull the CD player from the mount far enough to reach the wiring connections at the back of the player.
Unplug the harness adaptors from the left side of the CD player's rear panel. Disconnect the FM antenna cable by pulling the lead from the outlet on the right side of the stereo's rear panel.
If you do not have string to feed through the keys, pull the keys in staggered order to begin removing the CD player. Once you start, grab the rings at the opposite corners (diagonally) to remove the unit from the dash.
