RSNAV C7 Virtual Cockpit: Launch Planned for Q1 2027

We have secured agreements for production tooling and CPU supply, with the first production prototype expected in December 2026. We’ll share more details as development progresses.

The D4 version is planned to follow shortly after the C7 launch. A version for the B8 platform remains under consideration.

We aim to offer competitive pricing for a system that goes well beyond a digital instrument cluster. Planned features include support for the original Audi display, night vision, parking assistance, integrated VAG-specific diagnostics, and extensive integration with factory vehicle sensors.

Reservations for the C7 version will open soon, ahead of its planned launch in the first quarter of 2027. The platform is being developed for C7 vehicles from model years 2011 through 2018. Model, equipment and feature compatibility will be detailed before reservations open.

Development work combines factory vehicle sensor data with AI-based object recognition from an AHD camera. These prototype demonstrations use recorded vehicle sensor data alongside front-facing dashcam footage. They show work in progress; production features and compatibility will be confirmed in the release specifications.

Based in Montreal, Quebec, RSNAV is a boutique design and engineering firm specializing in aftermarket infotainment solutions for Audi vehicles. For the S5 range, we work with AINAVI in China on manufacturing, assembly and order fulfillment.

RSNAV handles product planning, software, UI/UX design and sales. AINAVI handles S5 manufacturing, custom assembly and logistics.

Before you buy

Genuine RSNAV-spec systems are sold through RSNAV.com. We do not distribute our proprietary configurations on AliExpress or other third-party marketplaces.

Our focus is ongoing software maintenance, vehicle-specific integration and audio tuning. Setup may require adjustments to suit your Audi’s factory equipment and your preferences.

Vehicle integration

Integration with Audi platforms from the 2010s, including 3G MMI, depends on the original vehicle equipment and the installed RSNAV configuration.

Volume display: The RSNAV on-screen volume indicator may not track adjustments made with the factory MMI volume knob.

Calls and audio: For supported configurations, we recommend using the factory Audi Bluetooth connection for calls while using RSNAV for media and navigation. Audio routing and microphone settings can affect call quality.

Power management: S5 startup, sleep and shutdown behavior is controlled by MCU firmware. Updated official builds address identified power-control issues. See the MCU notice at the top of this page and select the package for your screen and MCU type.

Orders and support

RSNAV systems are produced and assembled in small batches, so processing times vary by configuration. Please contact us for current availability and order updates.

Third-party forums and social-media groups are independent of RSNAV. For product specifications, troubleshooting and order support, please use our official support channels.

Vehicle-specific diagnostics

The C7 Virtual Cockpit is being developed with onboard VAG-specific fault-code reading and descriptions, alongside access to supported vehicle sensor data. This is an integrated diagnostic feature, not a replacement for the full functions of VCDS, ODIS or OBDeleven. Available functions will depend on the vehicle and installed control modules; the release specifications will detail what is supported.

Factory warnings across display modes

We are developing a way to bring supported factory warnings into the Virtual Cockpit interface, including while CarPlay or Android Auto is on screen. Development includes recognition of warning text from the original Audi display. Message coverage and language support are being validated; this should not be read as a guarantee that every warning or language is already supported.

Current production plan

Production tooling and CPU supply agreements are now in place. The first production prototype is expected in December 2026, with the C7 launch planned for Q1 2027. See the announcement above for the latest schedule and reservation updates.

The videos below show development prototypes. Final features and vehicle compatibility will be listed in the release specifications.

S5 remains part of the RSNAV product range as we develop the new Virtual Cockpit. The Virtual Cockpit project does not mean the S5 range is being discontinued.

Availability varies by vehicle, screen size and LTE region. Please check the relevant product page or contact rsnav01@163.com to confirm the configuration available for your vehicle before ordering.

For current pricing, please refer to the product pages.
