How do you program a 1999 Land Rover Discovery radio?

The 1999 Land Rover Discovery does not have a programmable radio. Instead, it comes with a factory-installed sound system with limited functionality. Depending on the specific car model and audio system variant, it typically features either a basic radio head unit with AM/FM radio capabilities or a cassette player combined with a radio. These early sound systems are not equipped with advanced features like CD players, navigation capabilities, or external device connectivity options and cannot be programmed in the same way as more modern vehicles.
