Supported Camera Types

• OEM Factory Cameras – integrate directly with the retrofit kit.
• Aftermarket Cameras – supported for both automatic and manual transmission vehicles.

Correct setup depends on camera type and vehicle transmission.

---

Step 1 – OEM Factory Camera Setup

1. Go to Settings → Reverse → Camera → Original.
2. Set Reverse Wire = OFF.
3. Guidelines and radar will display through the OEM system.
4. Keep all other reverse settings at default.

Step 2 – Aftermarket Camera (Automatic Transmission)

1. Connect the reverse camera to the CVBS port labelled “Reversing Camera”.
2. Connect the yellow cable labelled “12V Reverse Camera” to the camera power supply.
3. Go to Settings → Reverse → Camera → Aftermarket.
4. Set Reverse Wire = ON.
5. Leave Guidelines/Radar OFF unless the camera has built-in support.

⚠️ Note on Flickering (Manual Transmission Vehicles)

• Some Audi models use a CANBUS-controlled reverse light circuit.
• This often supplies a pulsed voltage signal instead of a clean 12V.
• Directly powering a camera from this circuit can cause the image to:
  • Flicker
  • Roll
  • Cut out (especially with engine running)

Solution:

• Install a relay or CANBUS stabiliser.
• Use the reverse light feed only as a trigger, and power the camera from a stable 12V source (ignition/accessory).
• This ensures a constant voltage and a stable image.

Step 4 – Extra Reverse Settings

• Reverse Option Delay: Adjust display time (0–15 seconds).
• Front/Rear Camera Mirror: Toggle ON/OFF if image orientation is wrong.
• Radar Options: Enable Reverse Radar ON if using OEM sensors.
