This document is provided to you free of charge, feel free to study and use it. At no stage do I assume responsibility for your actions or any of my writings that may mislead you. So, as with my other documents, I say use at your own risk.

Disclaimer: Use this guide at your own risk, we are not responsible.

Warning: If your car is equipped with a BOSE or B&O sound system (8RQ or 8RY), read the DSP section carefully.

Important: Connect the car to a charger or leave the engine running.

Important: Some users report problems when copying files from Mac OS / Linux, it is better if you use Windows for all file copying processes. You can use a virtual machine for this.

Recommended: Read the entire guide before starting, double-check all steps and follow them carefully.
