Installation & Support
Installing an Audi Android head unit may look complicated when you first see the wiring harness, but our systems are supplied with the components needed for your specific vehicle. We provide installation videos and remote support to help you through the process.
Before installation, we recommend sending us a photo of your dashboard and current MMI system. This allows our team to confirm the correct unit and configuration for your Audi.


Without a doubt, after seeing installation, the 12.3″ for B9 models sits way sweeter on the dash than the 10.25″. Our opinion stands for the A4/A5/S-Q & RS series.
