3. Setup and Installation
3.1 Important Compatibility Notes
This is a double DIN size product. Ensure your vehicle's original CD unit is also double DIN. This unit is not compatible if your vehicle has a single DIN size CD unit.
This head unit is compatible with your car's original BOSE system. However, if your Audi has a factory BOSE system, you may experience static noise or excessive loudness due to amplified outputs. An inline hi-lo adapter may be required to resolve this. XTRONS offers a quadlock-quadlock loom with inline hi-lo converters (e.g., ASIN: B083DNCQT1).
If your vehicle has an RNS-D (Radio Navigation System) or BNS 5.x (Basic Navigation System), this unit is not compatible. Please provide a picture of the original wiring for assistance.
