If your Audi A7 C8 has MHI2P MMI but no Android Auto, the infotainment system is missing one of the most practical smartphone features available for Android users. With Android Auto enabled, supported apps and phone functions can be accessed directly through the original screen and controls.
This product activates Android Auto in the factory MMI through RetroLab Pro. The activation follows a guided 2-step process and does not rely on patch files, software flashing, or modified firmware.
Android Auto is available as a wired function only on these compatible vehicles, so a USB connection is required during use.
After your order is confirmed, the activation is linked to your vehicle’s VIN. You connect the vehicle to a Windows PC using an ENet cable and follow the guided workflow inside RetroLab Pro. The app handles the required activation steps and enables Android Auto in the MMI.
This Android Auto activation is also available for other compatible Audi models:
Below are some common questions about Android Auto activation.
What changes after activation?
Android Auto becomes available in the original MMI, allowing supported Android apps and smartphone functions to be used through the factory interface.
Does this support wireless Android Auto?

Is this done with unofficial software modifications?
No. The activation is performed without patching, firmware modification, or software flashing.
How is the process completed?
The activation is carried out as a 2-step guided procedure in RetroLab Pro using your VIN-based entitlement.
Do I need to visit a workshop?
No. The activation is completed directly by you with RetroLab Pro, a Windows PC, and an ENet cable.
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).
