Introduction: Each manual gives you the help you need for your vehicle's sound system. It covers troubleshooting to locate problems and identify what needs to be repaired or replaced. It does not support non-factory system change outs but does give you guidelines on what you can do to upgrade. The information is useful to someone considering system change outs as it explains what's compatible with the factory equipment. It does not contain technical information such as schematics or internal component level repair. It does cover the stereo connector pin outs and what equipment can be easily added or changed to make the factory system better. Each manual is an extension of our website, to provide all the information we have concerning your vehicle.
