Audi RMC Firmware Update SD Card – RMC2 K16158 H5x / RMC4 P16342 H6x

Update your compatible Audi RMC infotainment system with the firmware package matched to its hardware generation and current software.

Choose between RMC2 K16158 and RMC4 P16342, supplied on a prepared SD card with installation instructions.

📌 Available Firmware Options

These packages are not interchangeable. The full software version and hardware index must be checked before installation.

🔧 When Is a Firmware Update Useful?

An update may be appropriate to address a documented software issue or meet the requirements of a supported upgrade.

Potential reasons include Bluetooth pairing, audio streaming, hands-free calling or system stability problems. The relevant fixes depend on your existing version; firmware is not a guaranteed solution to every fault.

If your system works correctly and no planned upgrade requires different firmware, updating may not be necessary.

🚗 Vehicle & System Compatibility

For selected European RMC-equipped vehicles:

• Audi A1 / S1
• Audi Q3 / RS Q3
• Audi A6 / S6 / RS6 C7
• Audi A7 / S7 / RS7 C7

Existing software normally begins RMC_EU. Vehicle model and year alone do not identify the correct firmware.

🔎 Check Before Ordering

Open MENU → Setup MMI → Version Information. Menu wording may vary.

🔊 Important for BOSE Vehicles

Do not manually select or force a BOSE amplifier update unless specifically instructed.

3. Select only the components specified in the instructions.

Installation typically takes 30–45 minutes.
