Compatibility Notes:
- This product is compatible with data-bus controlled amplified systems only. To identify these systems, look for logos on door speakers, tweeters, dash speakers or the subwoofer to confirm that the vehicle has a compatible amplified system. If you are unsure of your vehicle having an amplified system please contact an authorized Ford service center for further clarification.
- 2018-2019 Super Duty Trucks can have either Sony or B&O systems to be compatible.
- 2019+ Mustang must have B&O System to be compatible. If the amp looks like the one pictured, it is compatible. The amp can be found in the driver's kick panel. If the system is amplified and not badged then the AP4 is not compatible as this is a completely analog system.
