BMW Wireless Apple CarPlay & Android Auto

What is it?It is a small Multi Media Interface (MMI) box that will retrofit the following features to your BMW:
- Apple CarPlay (wired and wireless)
- Android Auto (wired and wireless)
- Apple AirPlay
- Screen Mirroring (wired) with Autolink
- Displaying 3rd party aftermarket camera video signals
- Basic USB playback from e.g. a thumb drive
The box uses the OEM mic and supports Siri and Google Assistant either via voice keyword (‘Hey Siri’ / ‘Okay Google’) or by long-pressing the steering wheel voice button.

How does it work?The MMI box essentially acts as an intermediary between your original headunit and display. While the box is inactive, the original video signal is passed through unchanged and your car works as before.
After activating the MMI box, the box’s video signal is shown on the display instead.
You can easily switch back and forth between the box and your original headunit. Using the MMI box is optional and should be seen as an add-on and not as a replacement.

Is my car supported?All cars roughly from 2013-2016 with ‘NBT’, ‘NBT EVO’ (ID4), ‘ENTRY’ and ‘ENTRYNAV’ headunits are supported.
Other headunit: ‘NBT EVO’ (ID5/ID6) is supported. ‘CIC’ is supported. Use different Cable harness.

Installation

Installation is the same for all aftermarket units like this (e.g. the 10.25″ android 9 displays).
The basic idea:

Disconnect the big ‘Quadlock’-cable from the original headunit
Connect the box’s Y-harness to that cable. The new quadlock goes into the headunit, the small power cable into the MMI box itself
Disconnect the LVDS cable from your original display and plug it in the box’s ‘LVDS in’ connector
Connect the 2nd LVDS cable to ‘LVDS out’ and plug that into the display instead

Important for step 2: If your original quadlock has a green 2-pin optical cable, you need to transfer that over to the new quadlock plug or otherwise you will not have any sound. If your quadlock does not have this cable, don’t worry, in that case you don’t have to do anything.
