• Data lines for communication between the radio and other vehicle systems (like steering wheel controls).
• Antenna connections.

Knowing how to read these symbols and follow the lines is key. For instance, a simple line might represent a direct wire, while a series of dots could indicate a ground connection. A legend is usually provided to explain each symbol's meaning.

Here’s a simplified representation of what you might encounter:
