CANbus Parking Buzzer Retention Interface – Retain Parking Sensor Audio

Restore essential vehicle audio alerts with this CANbus Parking Buzzer Retention Interface, designed to maintain factory parking sensor tones (PDC) and warning chimes when upgrading to an aftermarket head unit.

In many modern vehicles, parking sensor sounds and warning alerts are generated through the original stereo system. When this unit is removed, these important signals are often lost. This interface solves the problem by reading CANbus data and reproducing the audio through an additional speaker, ensuring your parking assistance system continues to function correctly.

Perfect for professional installers and advanced DIY users, the interface is compatible with a wide range of CANbus-equipped vehicles including BMW, Mini, Citroën, Peugeot, Ford and more.

In addition to restoring parking tones, the interface provides a configurable CANbus output, which can be used for ignition, speed pulse, reverse gear, or handbrake signals—making it highly versatile for advanced car audio installations.

Please note: this is not a plug-and-play solution and requires hardwiring to CAN High, CAN Low, ignition, and ground connections. Professional installation is recommended.
