Some Audi Q8 4M vehicles were delivered with MHI2P MMI but without Android Auto activated, despite the infotainment hardware being capable of supporting it. This leaves Android users without direct access to familiar navigation, media, and communication apps through the original factory display.
This product activates Android Auto in the original MMI using RetroLab Pro. The complete procedure is carried out as a guided 2-step activation and does not involve patching, software flashing, or modified firmware.
Android Auto is supported as a wired function only on these compatible vehicles, so a USB connection is required when using the feature.
After payment, the activation is assigned to your vehicle’s VIN. You connect the vehicle to a Windows PC using an ENet cable and carry out the activation in RetroLab Pro. The app guides you through both steps and enables Android Auto in the original MMI.
This Android Auto activation is also available for other compatible Audi models:

Starting from model year 2024, most Audi vehicles are equipped with SFD2 (Schutz der Fahrzeugdiagnose 2) security protection. This system prevents remote coding, dataset uploads and activations outside of authorized workshop environments.
If your vehicle has one of the following PR codes, it is protected by SFD2:
Vehicles with SFD2 cannot be activated remotely.
For these vehicles, we only offer installation and activation at our workshop in Vellinge, Sweden. If you are unsure whether your vehicle has SFD2, please contact us before ordering.
All coding, adaptations and feature activations are performed using RetroLab Pro. No third-party tools, scripts or manual coding are required.
Hardware installation must be carried out according to Audi factory repair manuals and wiring diagrams. We do not provide trim removal or mechanical disassembly guides.
You must be comfortable working on your vehicle or have a professional workshop perform the installation. Remote activation support is available if required (additional cost may apply).
