Compatibility comes first

Record vehicle year, make, model, trim and factory audio package. Identify whether the radio is integrated with steering controls, cameras, warning sounds or vehicle settings. A radio that fits the opening is not necessarily electrically compatible.

Use model-specific documentation and suitable harnesses or interface adapters. Avoid cutting original wiring as a first approach. This course explains planning, not a universal instruction for every vehicle.

Worked example

Two cars of the same model year can have different factory amplifiers and therefore require different adapters.

Try it yourself

Make a compatibility worksheet listing vehicle details, radio model, mounting kit and interface needs.
