The MDeck BA-2 Bluetooth Retrofit Kit seamlessly adds Bluetooth music streaming, voice assistance, hands-free calling, and AUX-IN to your factory BMW CM5905, CM5907, or CM5908 radio. The plug-n-play circuit board replaces the factory cassette deck inside the radio enabling a deep integration of modern audio tech that is leaps and bounds beyond any other solution on the market.

We design our MDeck kits to be as easy to install as possible. For the DIY installer, we create videos to walk you through step-by-step installation into each of the supported radios.

However, we also offer a mail-in installation service to install the parts of the kit that are internal to the radio, leaving only the microphone to install in the car. See the related items section above to add this installation service to your cart. When checking out with this service, your order confirmation will include instruction for mailing your radio to our shop.

CM5908

Video for BA-2 installation into the CM5908 coming soon. However, installation is nearly identical to installation of our previous version, the BA-1. The only important differences are that you can ignore any steps related to the RF shield as the BA-2 does not require one. Also, the microphone extension cable mentioned for the BA-1 is replaced by the mic/aux cable for the BA-2. The connector on the board is a different style, but otherwise everything installs the same.
