Ask a Saab dealer for >the codes? > >Cheers, Ben Ben, No radio code is needed for your car. The radio is "married" to your car by the car's VIN. The radio is on the interior CAN bus or I-bus. When the radio is turned on, it sends a request on the I-bus for the car's VIN. If the car's VIN matches the stored VIN in the radio, it functions, otherwise you will get a "Radio Code" message on the SID. In this case, the message indicates this radio is not married to this car. The radio may be married to another car or not married to any car. The stored VIN is the VIN of the car that was used to "Marry" the radio using the TECH II. This information is stored in the non-volitale memory of the radio. The information can only be changed, "Divorced", by the TECH II if the stored VIN and car VIN match. Thus making it impossible to use an undivorced (stolen) radio (or CD Changer) in another car. This information is valid for 1999-2003 conv US spec 9-3 and All US spec 9-5 All you will have to do after changing the battery is to set the SID and recallibrate the ACC if you have one. Good luck, Steve Crowe, Master Saab Tech Harpers Ferry, WV
