Audi A3 updates for the North American region
This category covers selected infotainment updates for Audi A3 vehicles originally configured for the USA, Canada and Mexico. Available products include navigation maps, individual firmware packages and additional compatible upgrades.
The correct product must be selected using the complete software train shown by the vehicle. A North American Audi A3 can use different systems depending on its generation, equipment and production date.
| Software prefix | System family | Important check |
|---|---|---|
| MHIG_US_AU | MIB1 High | Match the complete MHIG_US_AU firmware train. |
| MHS2_US_AU | MIB2 Scale | Do not confuse MHS2 with MHI2. |
| MHI2_US_AU37x | MIB2 High | The complete AU37x hardware branch must match. |
| MHI3_US | MIB3 | Confirm the full MHI3 train and compatible vehicle hardware. |
US and European firmware are different
North American firmware usually contains a US designation, while European firmware uses EU or ER branches. Do not install European firmware as a normal update on a North American unit. Changing the software region is a separate conversion procedure.
How to choose the correct Audi A3 update
- Open the Version Information screen in the vehicle.
- Record or photograph the complete current software version.
- Identify the firmware family, hardware branch and region.
- Compare the full version with the compatibility information on the product page.
- Check whether the product contains firmware, maps, activation or only one of these components.
How to identify your Audi infotainment system and firmware version
Firmware, maps and activation are separate components
A single firmware product normally contains only the selected firmware and its installation instructions. It does not automatically include navigation maps, a map license, Apple CarPlay or Android Auto activation.
A navigation map product may also require a suitable firmware version or an existing map license. Always check the individual product description before ordering.
Do not choose an update by model year alone
Two Audi A3 vehicles from the same production year can use different infotainment systems. Installing a package intended for another firmware family or region can cause update errors or loss of system functions.
Installation information
Installation procedures depend on the installed infotainment system and selected product. For compatible MIB2 firmware and map products, use the following guides together with the product-specific instructions:
Frequently asked questions
Which update does my North American Audi A3 need?
Check the complete software version and select a product intended for the same firmware family, hardware branch and region.
Will European firmware work in a US Audi A3?
Not as a standard update. European and North American firmware belong to different regional branches. Region conversion is a separate procedure.
Does a firmware update include North American maps?
Normally no. Maps are included only when the individual product is described as a bundle containing both firmware and navigation data.
Does firmware activate Apple CarPlay or Android Auto?
Not automatically. Smartphone interface activation is included only when the individual product description explicitly confirms it.
Are the same updates used in the USA, Canada and Mexico?
These markets commonly use North American software branches, but compatibility must still be verified from the complete software version installed in the vehicle.
Not sure which product matches your Audi A3?
Use the Audi Check Upgrade tool and enter the complete firmware version exactly as displayed by the vehicle.
