2021-2024 Audi HUD Navigation Not Displayed TSB

Audi has released Technical Service Bulletin (TSB) 2071920/1, dated October 26, 2023, to address customer inquiries regarding navigation instructions not appearing on the Head-Up Display (HUD) in various 2021-2024 Audi models. This bulletin provides an important clarification for owners experiencing this specific behavior, confirming that the absence of turn-by-turn guidance on the HUD is an intended design characteristic.

Symptoms

Owners of affected Audi vehicles, including the A4, A4 allroad, S4, A5, A5 Cabriolet, A5 Sportback, S5, S5 Cabriolet, S5 Sportback, RS 5, RS 5 Sportback, Q5, Q5 e quattro, Q5 Sportback, SQ5, and SQ5 Sportback models from 2021-2024, may observe that "turn-by-turn guidance is not depicted on the Head-Up Display (HUD)". This means that while the navigation system functions correctly on the main infotainment screen, the directional prompts and other route details do not project onto the windshield via the HUD. This is the primary symptom of the Audi HUD navigation not displayed condition.

Technical Background

According to Audi, the navigation turn-by-turn instructions are indeed requested from the control unit for information electronics -J794- (address word 5F). However, these instructions are intentionally not displayed in the Head-Up Display due to what Audi describes as "conceptual reasons". Essentially, the navigation turn-by-turn instructions were not designed or implemented to be shown on the head-up display, and therefore cannot be depicted. This is not a malfunction but rather a design choice by the manufacturer.

Important Warnings for Owners

Audi's Technical Service Bulletin 2071920/1 provides critical guidance for both technicians and owners regarding the Audi HUD navigation not displayed condition. The bulletin explicitly states:

• "No repair is available at this time."
• "Do not perform any repairs. Any repairs for this concern may be denied."
• "Instruct the customer that this condition is normal."

This means that the absence of navigation instructions on the HUD is an intended design characteristic, not a fault requiring intervention. Owners should be aware that attempting to have this condition 'fixed' at a dealership will not result in a repair, and any associated charges may not be covered under warranty. The TSB also clarifies that it is "informational only and not applicable to any Audi Warranty", reinforcing that this is not a defect.

What This Means for Owners

For owners of 2021-2024 Audi A4, A5, Q5, S4, S5, RS 5, SQ5, and allroad models equipped with a Head-Up Display, experiencing the "turn-by-turn guidance is not depicted on the Head-Up Display (HUD)" message or simply noticing the absence of navigation prompts on the HUD, this bulletin confirms that your vehicle is operating as designed. There is no underlying fault, and no repair is needed or available. This information helps to prevent unnecessary diagnostic time or repair attempts for a characteristic that is considered normal by the manufacturer.
