MR12volt High-End Wireless Apple CarPlay & Android Auto MOST Interface – BMW NBT ID4 – P3000-BMID

Upgrade your BMW NBT ID4 infotainment system with the MR12volt P3000-BMID Wireless Apple CarPlay and Android Auto interface.

Designed for compatible BMW models equipped with the NBT ID4 system and MOST fibre optic audio network, MR12volt adds modern smartphone connectivity while retaining the original display, iDrive controller, factory amplifier and OEM vehicle functionality.

Unlike many aftermarket CarPlay interfaces that rely on the vehicle's AUX input, MR12volt integrates directly through the digital MOST fibre network. This helps preserve factory audio quality while adding Wireless Apple CarPlay, Wireless Android Auto, Bluetooth audio, camera support and advanced DSP tuning.

Factory Integration – Not a Screen Replacement

The MR12volt P3000-BMID is designed to work with the BMW equipment already fitted to the vehicle.

It does not replace the factory screen or head unit.

Your original:

• BMW display
• NBT ID4 system
• iDrive controller
• Factory amplifier
• Steering wheel controls
• Parking sensor display
• Vehicle menus

remain in place.

MR12volt adds modern smartphone functionality on top of the original system, making it ideal for owners who want newer connectivity without changing the appearance of the interior.

Why Upgrade Your BMW NBT ID4 System?

BMW's NBT ID4 infotainment system remains highly usable, but it lacks the smartphone integration expected from a modern car.

MR12volt brings the system up to date with:

• Wireless Apple CarPlay
• Wireless Android Auto
• Wired Apple CarPlay
• Wired Android Auto
• Direct MOST fibre optic audio
• OEM iDrive controller operation
• OEM microphone support
• Bluetooth audio streaming
• Camera inputs
• 15-band DSP equalisation

Direct MOST Fibre Optic Integration – No AUX Required

One of the main advantages of MR12volt is its direct integration into the BMW MOST fibre optic network.

Many aftermarket CarPlay systems rely on the vehicle's AUX input for audio.

This means the sound is passed through an analogue audio connection before reaching the factory audio system.

MR12volt instead uses the MOST network.

This provides:

• No AUX connection required
• Direct digital audio transmission
• No unnecessary analogue conversion
• Factory amplifier compatibility
• Preserved factory sound quality
• Cleaner OEM-style integration

For owners with BMW HiFi or Harman Kardon systems, this can be a particularly important advantage over simpler AUX-based interfaces.

Factory Audio System Compatibility

The P3000-BMID is designed to work with compatible BMW factory audio systems, including:

• Base audio
• HiFi
• Harman Kardon

The factory amplifier remains in use rather than being bypassed.

This allows MR12volt to integrate into the vehicle's original audio architecture while adding modern smartphone connectivity.

Wireless Apple CarPlay

The MR12volt P3000-BMID adds Wireless Apple CarPlay to compatible BMW NBT ID4 vehicles.

Once paired, compatible iPhone apps can be displayed through the original BMW screen and controlled using the factory iDrive controller.

This includes:

• Apple Maps
• Google Maps
• Waze
• Spotify
• Apple Music
• Podcasts
• WhatsApp
• Phone calls
• Messages
• Siri

Wireless connectivity means your phone can connect automatically after the initial setup.

Wired Apple CarPlay is also supported.

Wireless Android Auto

Android users can also benefit from Wireless Android Auto.

Compatible applications include:

• Google Maps
• Waze
• Spotify
• YouTube Music
• WhatsApp
• Phone calls
• Messaging
• Google Assistant

Wired Android Auto is also supported.

For BMW models that never received factory Android Auto, this is one of the biggest advantages of the retrofit.

Factory iDrive Controller Operation

The MR12volt interface is operated using the original BMW iDrive controller.

No separate aftermarket controller is required.

Once launched, Apple CarPlay and Android Auto can be navigated using the same controls already fitted to the vehicle.

This helps retain the familiar OEM experience.

Access Through the Factory TV Source

MR12volt integrates through the factory TV function within the NBT ID4 system.

To launch the interface:

• Open the factory media menu
• Select TV
• The MR12volt interface launches
• Use the original iDrive controller to navigate

MR12volt simulates the factory TV module as part of its integration.

Important – TV Coding May Be Required

If the vehicle does not already have a factory TV module, the TV function must be coded into the vehicle before MR12volt can operate.

This is an important installation requirement.

If you're unsure whether the TV function is currently enabled, this should be checked before installation.

Factory TV Module Vehicles

If a factory TV module is already fitted, it must be bypassed during installation.

Please note that an optical loop connector is not included with this package.

If a loop connector is required for your installation, it must be sourced separately.

Professional installation is recommended.

OEM Microphone Support

The P3000-BMID supports integration with the original BMW microphone.

This allows compatible handsfree calling functionality to use the factory microphone rather than requiring an aftermarket microphone to be visibly mounted inside the cabin.

For owners who want the installation to remain as OEM-looking as possible, this is a useful feature.

Steering Wheel Controls Retained

Compatible factory steering wheel controls remain operational with the MR12volt system.

This allows common media and telephone functions to remain accessible without changing the normal driving controls.

Factory Parking Sensor Display Retained

The original BMW parking sensor display remains available.

MR12volt works alongside the factory infotainment system rather than permanently replacing it.

This allows you to switch between Apple CarPlay or Android Auto and the original BMW menus when required.

Factory Display Retained

The original BMW display remains in use.

There is no need to install a replacement touchscreen or aftermarket display panel.

This helps maintain the original dashboard design and factory appearance of the vehicle.

15-Band DSP Equalizer

MR12volt includes a built-in 15-band DSP equalizer.

This allows additional audio tuning to suit the vehicle's factory speaker and amplifier setup.

Independent volume control is also available for:

• Navigation
• Media
• Microphone

This gives owners substantially more adjustment than many basic CarPlay retrofit interfaces.

Apple Lossless Support

Apple Lossless audio is supported.

Combined with the direct MOST fibre optic connection, this makes the MR12volt system particularly appealing to owners who want to maintain the performance of their factory BMW audio system.

Bluetooth Audio & Handsfree Calling

The system supports Bluetooth audio streaming and handsfree telephone calls.

Enhanced Bluetooth call functionality is designed to provide improved clarity while integrating with the factory vehicle system.

Reverse Camera Support

The P3000-BMID includes support for aftermarket reversing cameras.

Cameras up to AHD 1080P resolution can be used with the system.

This gives owners the option to add a reversing camera at the same time as upgrading the infotainment system.

Front & Blind-Spot Camera Inputs

Additional camera inputs include:

• Front camera
• Left blind-spot camera
• Right blind-spot camera

This provides additional flexibility for more advanced camera installations.

Wireless MirrorLink

Wireless MirrorLink is available for compatible Android devices using CarLetter.

This provides another smartphone connectivity option in addition to Android Auto.

USB Video & Music Playback

MR12volt supports compatible USB music and video playback.

This provides another media source alongside:

• Apple CarPlay
• Android Auto
• Bluetooth streaming
• Factory BMW media functions
