The Saab 9-3 comes with many options regarding stereo equipment. In the case of a malfunctioning stereo unit, you will need to remove the factory deck to perform repairs or to replace the stereo altogether. Saab stereos require DIN release keys to extract the factory decks. The DIN release keys are similar to the Ford DIN removal tools, and makes removing the stereo simple.
Open the bonnet of the Saab. Loosen the bolt on the clamp of the negative battery cable with the 10mm wrench. Remove the negative battery cable from the negative battery lead post.
Insert the DIN release tools into the openings on either side of the Saab stereo faceplate.
Pull outward on the release tools while simultaneously pulling the stereo from the dashboard. Pull the stereo far enough so that the wiring connections to the rear of the radio can be reached by hand.
Disconnect the wiring to the back of the Saab radio. There will be four groups of connecting wires connected to the stereo. The antenna, the speaker wires, the amplifier patch cables and the power supply cable all need to be removed from the rear of the radio to detached the radio from the Saab completely.
Place the negative battery cable clamp around the negative battery delete post. Tighten the clamp with the 10mm wrench.
If you need to install another stereo before operating the vehicle, leave the negative battery cable disconnected until your work is finished.
