Audi A3 8V Golf7 USB Android Auto Carplay retrofit

This adapter allows you to have Android Auto and CarPlay without losing the original adapter in your Audi A3 8V
To avoid losing the original adapter, you must make a Y-shaped detour from the original power supply. I did this directly near the rectangular green connector, behind the stereo unit. Pay attention to the polarity! Follow the same path as the cable provided with the Golf 7 USB adapter. I take no responsibility.

adapter: 5Q0035726E is cheap, only 30$

I added the lettering and a two-color profile.
You can easily change the materials and colors.
