How do I find the complete software version?

It means the entire infotainment software identifier, often called the SW train. It contains letters, numbers and other characters. A single abbreviated version or the vehicle model alone is insufficient for our check.

The route depends on the manufacturer and installed system. Open the version information or service menu of your infotainment system. Our vehicle check provides suitable guidance and example images. Only view the information there; do not start an update speculatively.

Photograph the entire version screen clearly and without reflections. Every character in the identifier must be legible. Do not use values from an example photo or a similar vehicle.

Some systems also require the four-digit MU version. The form only marks it as mandatory when needed for the specific check. Copy leading zeros exactly as displayed.

Do not guess or order based only on the vehicle's year. Use the help in the vehicle check or send us a clearly legible photo of your version screen for clarification.
