Audi A4/A5/Q5 CarPlay Display Upgrade Guide

Installation Overview

This upgrade allows for enhanced infotainment features, including Apple CarPlay, for compatible Audi models.

Wiring Components

The upgrade kit includes several cables and adapters:

• Main Power Cord
• GPS Antenna
• 4G Antenna
• LVDS Adapter Cable
• Gateway Interface-CAN cables
• CD Host Cable
• Power Cable (with various outputs like AUX-OUT, ACC-OUT, DVR-PWR, CAM-PWR, GND, CAN3-H, MMI I/F, CAN3-L, 360-DET, DVR-CVBS, CCD-AHD/CVBS)
• USB Cable
• Host Power Cord Plug
• Filter & Fuse Box
• AMI-AUX Cord (for specific audio setups)

Connection Procedures

CAN Bus Connection

The connection point for the CAN bus depends on your car's original radio system:

• For 3G MMI radio systems: Connect to the CAN bus socket located behind the passenger side storage box.
• For Concert/Symphony radio systems: Connect to the CAN bus socket located behind the air conditioning control panel.

Power and Audio Adapters

Connect the power and audio adapters to the rear panel of the original Audi host or to the original wiring harness removed from the Audi host.

Camera Integration

• The yellow RCA socket, labeled "CCD-AHD/CVBS", is for video input from an after-sales rearview camera.
• The "CAM PWR" cable serves as the trigger wire for the reversing camera. Connect this wire to the camera's red wire to ensure the screen switches to the camera view when reversing.

MMI and LVDS Connection

• Connect the MMI I/F to the LVDS socket to restore the functionality of the MMI button.
• Connect the LVDS cable (from the original Audi display) to the car's LVDS port. Failure to do so will prevent the display of original Audi car computer information and the rear-view camera.
• Note: LVDS sockets are found on the back of the original monitor and may be MMI or non-MMI types.

Center Speaker Connection

To connect the center speaker cable: Remove the original center console horn, then insert the two plugs from the cable into the socket and the horn respectively.

Operation and Settings

Switching Interfaces

To switch between the new upgraded interface and the original Audi car computer interface, click the "Audi MMI" icon on the main screen.

Troubleshooting Display Issues

If the original Audi screen displays incorrectly, especially with 3G MMI systems, it may be due to mismatched resolution parameters. Adjust settings as needed.

Audio Setup

Ensure the audio source is set to 'External Audio Input (AUX)'. If your system displays "AMI" instead of "AUX", connect the provided Audi AMI-AUX cable to the AMI port in the passenger side glovebox. This will switch the screen option to AUX.

Factory Settings and Vehicle Model Selection

• Access Factory Settings by inputting the password: 8866.
• When selecting the vehicle model, choose a year range and model name that matches your Audi. Examples include:
  • 09-12 B8 Concert/Symphony
  • Q3 PQ35 3G MMI
  • B9 MIB High-res / Low-res
• Refer to the provided serial number guidelines for specific model year compatibility (e.g., serial numbers 4, 5, 17 for 2009-2012; 17, 16, 13 for 2013+).

Camera Settings

• If your car is equipped with a factory-installed rear-view camera, select 'Original Camera'.
• For after-sales reversing cameras, choose the setting that matches the camera format and connect the camera cable to the back of the screen.
• Connect the video input cable (typically yellow connector, labeled "CCD-AHD/CVBS") and the reverse line ("CAM-PWR"). The power supply for the camera should be connected to the reversing light (+ and - wires).
