UNICHIME Universal chime interface

Description:

The Aerpro UNICHIME Universal Chime Interface allows you to retain a vehicles original parking tones when upgrading to an aftermarket stereo. With an aftermarket audio system, certain features, like parking tones, can become lost via the CAN system.

Important Information:

This product should be used when safety tones (reverse sensor audio, seat belt/car door open chimes) would not be retained when upgrading to an aftermarket stereo.
This product needs to be used in addition to a separate ISO harness or steering wheel control interface, should you wish to retain those features.

Features:

Compatible with select BMW, Citroen, Land Rover and Peugeot vehicles
