How does the changer emulator work?

is cheating on your radio by pretending to be a standard CD changer. The device transforms music from Bluetooth or AUX input and creates a standard compatible with your CD changer, understood by your radio. Don’t worry, it’s completely safe for the radio.

Installing the emulator

Installation is very simple, because the equipment manufacturers have equipped the product with a dedicated 12-pin Fakra or 8-pin plug for the models listed below. Just plug it into the back of the radio and you can enjoy new functions without interfering with the car’s electrical system. The MP3 changer also requires no additional power supply. So do not think about batteries, power supplies, or pulling the cable from the cigarette lighter around the cockpit. The small size of the module will not cause you any problems during the installation and you can easily fit it in the glove box, armrest or any other convenient place for you.

Steering wheel control and speakerphone

The device will be interpreted as a typical CD player, so you will be able to control it from the multifunction steering wheel (if your car has one). In addition, it can be used as a speakerphone. It automatically mutes the music flowing from the changer on an incoming call and makes it loud after the call. This model of the emulator has additional “MUTE”, “TEL +” and “TEL -” cables, thanks to which, when properly connected to the radio, even when listening to music from a source other than the changer, the sound will be muted (when a connection comes in), and You will hear a short ringing signal from the speakers. To answer a call, simply press the “CD” button on the radio. An external microphone is also included.

Music streaming thanks to A2DP technology and more

The emulator gives you the ability to stream music from your phone directly to the speakers (using Bluetooth A2DP) or connect any audio source via the AUX socket (e.g. mp3 player, phone, iPhone). No more CDs and losing songs from your phone to memory cards.
