Our retrofits emulate a CD changer. Your MMI system "thinks" that another CD changer is connected.

The MMI 2G Basic can only manage one CD changer. If you want to retrofit Bluetooth, you have to deactivate the CD changer. This is very easy and is explained in the instructions. The instructions are available for download at the product side in this shop. And then simply copy your CDs to your smartphone or to the cloud and listen to them wirelessly via Bluetooth. The MMI 2G High can manage two CD changer.
