The process of exchanging the original audio head unit in a specific sport utility vehicle with an aftermarket or OEM (Original Equipment Manufacturer) alternative constitutes a vehicular audio system modification. This typically involves disconnecting the factory-installed receiver and installing a new one, often to upgrade features or address malfunctions. For example, a malfunctioning factory radio in a 2016 RAV4 may prompt the owner to consider purchasing and installing a modern touchscreen unit with integrated navigation and smartphone compatibility.
Altering the factory entertainment system allows vehicle owners to enhance their in-car experience. Benefits may include improved sound quality, expanded connectivity options (such as Bluetooth and Apple CarPlay/Android Auto), and access to advanced features like GPS navigation, satellite radio, and backup camera display. Historically, this type of modification was primarily for improved audio fidelity; now, it frequently addresses technological obsolescence and integration with modern mobile devices.
