Benefits of using an original multimedia module

Using a factory MMI module in the Audi TT FV provides a number of practical advantages in daily vehicle operation:

• maintaining full integration with the vehicle's data bus and onboard systems,
• proper cooperation with the factory screen and center console controls,
• support for GPS navigation and SD data media in accordance with the manufacturer's standard,
• a consistent user interface matched to the design and logic of Audi systems.

Thanks to this, the comfort of multimedia operation remains at the level intended by the manufacturer, without the need for additional adapters or compromise mounting solutions.

Application in repairs and upgrades of Audi electronics

The MMI multimedia module from this offer is particularly useful for infotainment system repairs when the existing control unit has suffered a logical or mechanical failure.
