Exact Vehicle Compatibility

Use the table below to match your vehicle and factory audio equipment. A year and model match by itself is not enough—the factory amplifier, premium-audio system, radio connector, screen and option details shown for the application must also match.

Compatibility & Installation Requirements

• Factory system: compatible factory Bose amplified system with GM IO5 or IO6 infotainment.
• System design: This interface adds subwoofer-level outputs; it does not replace the factory radio, factory amplifier, aftermarket amplifier, or subwoofer.
• Signal and power: The aftermarket amplifier or powered subwoofer requires appropriate power/ground wiring and RCA signal cables.
• Programming: Use current PAC firmware and follow the current application guide for the exact vehicle.
• Requires factory Bose audio and GM infotainment RPO code IO5 or IO6.
• Verify the RPO label or QR-coded GM door-jamb label before ordering.
• The factory radio and factory amplifier must remain connected and operational.
• Professional installation and system tuning are strongly recommended.
