A car ISO to DIN plug is an adapter used to connect car audio systems with different types of connectors. It is commonly used when upgrading or replacing a car stereo to ensure compatibility between the vehicle's wiring and the aftermarket radio or audio equipment.

Explanation:

• ISO Connector: Also be called ISO 10599 Connector. This is the standard connector used in most European cars for car radios and audio systems. It has a rectangular shape with specific pin configurations for power, ground, speakers, and other functions.
• Din Connector: Also be called DIN 41585 connector. A round connector used in older car radios and some audio systems. It typically has a standardized pin layout.

Usage:

When you have a car with an ISO connector and want to connect it to a radio or device that uses a DIN plug, the ISO to DIN adapter provides the necessary connection. This allows you to seamlessly integrate the new stereo without rewiring the entire system.

Example:

• If you're replacing a factory car radio (with ISO connections) with an older model radio (that has a DIN plug), the ISO to DIN adapter will bridge the connection, allowing the system to work properly.

These adapters make installation easier, especially when working with different standards in car audio systems.
