What information does a compatibility check require?

Give the manufacturer, exact model, year and desired smartphone function. For remote activation, we also need the full version information and, if required for your system, a photo of the USB socket. This USB check is not required for Porsche and confirmed VW Touareg MH2p systems. A separate process applies to enquiries about coding in person.

The software train contains letters, numbers and underscores. An abbreviated version or a photo of a similar vehicle is insufficient. Photograph the entire version screen clearly and do not copy values from example photos.

A photo of the socket including any visible markings helps us assess it. A smartphone charging does not prove a data connection. Navigation, sound system and existing activation messages may also be relevant.

Software activation, the data connection and any required update are separate matters. A charge-only socket may require suitable hardware changes even if activation is possible. This does not automatically confirm suitability.

Photo recognition can only suggest visible values. Compare and confirm them before submitting. If information is incomplete or inconsistent, we first clarify the technical combination rather than assume suitability.

For the solutions offered for VW, SEAT, Škoda and Audi, codes such as MST2, MHI2 or MHS2 may appear. They represent different hardware and software variants. We therefore need the full installed software code and the required photos. A prefix alone does not confirm compatibility.

With the infotainment system switched on, hold the menu button on the screen for about three to five seconds. In service mode, open “Software-Aktualisierung / Versionen” (software update / versions) and photograph the full installed SW Train and MU version. Do not start an update.

On an Audi with MH2p, open settings → general → version information. Photograph the entire screen and the USB port. The VW Touareg button combination does not apply here.

MST2 includes different hardware variants. Our check assesses European Technisat codes containing ZR or PQ and ending in T separately from Delphi codes ending in D. “MST2” alone is therefore not enough: photograph the full code. Our offered MST2 activation also requires navigation to be present.

No. We check a confirmed update target within the same version generation. Upgrades across generations are not offered; our activation method does not support Technisat versions above 480T. A higher number is therefore not a general upgrade recommendation. Do not install files on speculation.

The version screen describes the infotainment system, while the USB photo shows the port actually fitted. A similar port or an example photo does not confirm a data connection. Please photograph your port with good lighting and no cable inserted.
