Audi A5 European MMI Firmware Updates

Browse individual firmware updates for compatible European Audi A5 infotainment systems, including MIB3, MIB2, MIB2 Scale, MMI 3G and MMI 2G. Available software trains include MHI3, MHI2, MHI2Q, MHS2, HN+, HNav, BNav and S1_B8.

Firmware compatibility depends on the installed infotainment unit and its complete software version. Check the MMI version before ordering; the Audi A5 model year or navigation region alone is not enough to identify the correct update.

Check the complete software version before ordering

Firmware packages for MHI2, MHI2Q and MHS2 are different and cannot be interchanged. The same applies to MMI 2G and MMI 3G software families. Follow our Audi MMI identification guide to find your system version, or use the Check Upgrade service if you need help confirming compatibility.

Single firmware updates for the European Audi A5

This category contains individual firmware packages for selected European Audi A5 infotainment systems. The available products cover several generations and hardware families. Choose an update by matching the complete software train shown in your vehicle with the firmware product information.

Firmware compatibility is system-specific

Do not select firmware only because the product mentions Audi A5 or appears to have a higher version number. MHI2, MHI2Q, MHS2, MHI3, HN+, HNav, BNav and S1_B8 are separate software families. Check the complete current version and the product instructions before ordering.

Firmware families listed for Audi A5

Firmware is separate from maps and feature activation

A single firmware update changes the infotainment system software. Navigation maps, map licences and Apple CarPlay or Android Auto activation are separate items unless a product explicitly states otherwise. Check the individual product description for exactly what is included.

Before purchasing an update

  1. Open the MMI version information screen and note the complete software version.
  2. Identify the software family, such as MHI2Q, MHS2, HNav or BNav.
  3. Compare the installed version with the product’s compatibility details and update path.
  4. If you are unsure, use the Check Upgrade service before ordering.

Frequently asked questions

Can I choose firmware using only my Audi A5 model year?

No. Different infotainment platforms and software trains may be used across Audi A5 model years and configurations. Check the complete software version shown by your MMI before selecting firmware.

Can I install MHS2 firmware on an MHI2 or MHI2Q system?

No. MHS2, MHI2 and MHI2Q are different software and hardware families. Use only a package confirmed for the complete version installed in your vehicle.

Does a single firmware update include navigation maps?

Not unless the product explicitly says it is a bundle. Single firmware products contain firmware; maps and any required map licence are listed separately.

Will firmware alone activate Apple CarPlay or Android Auto?

No. Firmware updates and smartphone feature activation are separate. Check the product description for the features included with a specific package.
