How to Activate Traffic Sign Recognition on Audi Q8 4M

Once activated, Traffic Sign Recognition on your Q8 4M uses the front camera (PR-QK1) to detect road signs in real time:

• Speed limit signs displayed directly in the Virtual Cockpit or Instrument Cluster Top
• No-passing zone indicators shown when relevant
• End-of-restriction signs automatically clear the displayed restriction
• Navigation integration supplements camera data with map-based speed information for improved accuracy

This is a full activation — not just a coding change. RetroLab Pro configures the camera module, links it to the cluster, and enables the complete data pipeline. The result works exactly as if it were factory-activated.

Traffic Sign Recognition is available on Audi Q8 4M models from 2018 to 2023 — EU and NAR markets, SQ8 and RS Q8 included.

Required hardware:

• Front Camera (PR-QK1)
• Virtual Cockpit or Instrument Cluster Top
• Navigation System

The method (and price) depends on your exact model year:

• 2018, 2019, 2020: activation runs directly through the RetroLab Pro app — no dealer, no remote session.
• 2021, 2022, 2023: activation can only be run through a guided remote session on a Windows PC + ENet cable.

Both paths deliver identical OEM behaviour on the car — the difference is purely in how the activation is performed.

2018–2020 (App activation): Windows PC + ENet cable, or iPhone 15/16/17 + USB-C to LAN adapter. Price: €100, one-time, permanent, VIN-verified.

2021–2023 (Remote session only): Windows PC + ENet cable required. Price: €300, one-time, permanent, VIN-verified.
