Vehicle Compatibility

This radio unit may be suitable for selected Audi A4, A4 Allroad, A5, A6, A6 Allroad, A7, Q3, Q5 and Q7 vehicles equipped with a compatible factory MMI system.

Selected S and RS applications may also use this part depending on the vehicle's production date, market and original infotainment equipment.

Compatibility depends on the MMI generation, market region, radio-frequency specification, speaker system, amplifier arrangement, television or digital-radio equipment, hardware version and software configuration.

Please compare part number 4G0035056G, all additional label numbers, connectors and factory equipment codes with the original radio unit before purchasing.

Similar-looking Audi radio units may contain different regional tuners, software or audio-output configurations and should not be considered interchangeable solely because the housing and connectors appear identical.

Audio-System Compatibility

This module is associated with selected standard or active-speaker audio configurations. It should not automatically be considered a replacement for a separate Bose or Bang and Olufsen sound-system amplifier.

Vehicles equipped with premium factory audio may use an additional digital sound-system amplifier with a different part number and coding configuration.

Coding and Programming Requirements

Coding and component-protection commissioning should generally be expected when installing this radio unit into a different vehicle.

The replacement module may require component-protection removal, vehicle-specific coding, adaptation and software configuration using Audi-compatible diagnostic equipment with authorised online access.

The module must be configured to match the vehicle's market, MMI system, radio equipment, speaker arrangement and installed infotainment options.

A replacement unit may provide restricted or unavailable audio operation until component protection has been removed. A used unit from another vehicle should not be considered plug-and-play.

If the vehicle's original unit is professionally repaired and reinstalled into the same vehicle, additional component-protection removal is not normally required.

Installation Information

Professional installation by an Audi technician or experienced automotive infotainment specialist is strongly recommended.

The vehicle should be diagnostically scanned before replacement to confirm that the radio unit is responsible for the fault. The antennas, speakers, wiring, power supply, earth connections and MOST fibre-optic network should also be inspected.

The installation area should be checked carefully for water entry, moisture and corrosion before the replacement unit is fitted.

After installation and commissioning, radio reception, speaker output, MMI controls, audio balance, fade and communication with the factory infotainment system should be tested.
