Audi A6 C6 Front Camera Installation with Signal Splitter

Upgrade your Audi A6 C6 with a DIY front camera installation using a 4-in-1 video signal splitter and an Android head unit. Though not originally supported, it's easy to add front, side, and reverse cameras with this setup.

Parts used:

• Android Head Unit: https://s.click.aliexpress.com/e/_oErW5XZ
• Reverse camera: https://s.click.aliexpress.com/e/_oEi7QST
• 4-in-1 video splitter: https://s.click.aliexpress.com/e/_oDSHCEL
• Side cameras: https://s.click.aliexpress.com/e/_oEt4U0f
• Front camera: https://s.click.aliexpress.com/e/_opzeIsr

Splitter setup:

• Video output → Android HU video input (RCA)
• “REVERSE” trigger wire → steering cable from splitter

Relay wiring for front camera (triggered by brake lights):

• 30: +12V from fusebox
• 86: Ground
• 85: Brake light signal (red/yellow for LED lights)
• 87: Power to front camera

Power:

• Splitter gets ACC power from the driver-side fuse box.

Notes:

Because reverse camera shown a mirrored view after connecting front camera through splitter I got mirrored view (left and right). I had to replace the rear camera with one that can toggle mirror mode by cutting a wire.

Android radio applies mirror/parking line settings to all cameras, so I have turned off parking lines.

Planned upgrade: Add a NE555 time delay relay to keep front cam active for N seconds after brake release.

Perfect DIY project for enhancing safety and convenience on your Audi A6 C6!
