Audi A8 4H MMI 3G and 3G Plus smartphone integration kit with fibre optic audio and OEM controls

Part number: P2000 3G8MM

Give your Audi A8 4H a modern connectivity lift with a factory-style smartphone link that keeps the original screen, rotary knob and steering wheel buttons. This Mr12Volt P2000 module connects to the car via the M.O.S.T. fibre optic network for clean, digital sound and uses the built-in microphone for crystal-clear voice control. It looks stock, feels stock and delivers the features you expect from a premium infotainment upgrade.

We have fitted and tested this unit extensively at MJ Modifications and the feedback from A8 owners has been superb. Fast boot-up, rock-solid wireless performance, excellent call quality and audiophile-grade playback through the fibre bus make this the go-to integration kit for MMI 3G and MMI 3G Plus cars.
