Notes
MIB2 systems with identifiers such as MST2, MHI2 or MHS2 may be suitable for activation. The identifier alone does not authorise a purchase. The described MIB2 units without navigation and with only one SD card slot are not supported by this offer.
A socket marked “Charge Only” is insufficient for a smartphone data connection. A suitable USB socket with wiring and coding may be required on affected devices. Update requirements also need clarification for premium sound systems.

Frequently asked questions and limitations
Is every MIB2 device suitable?
No. The device variant, full software version and equipment must match. Identifiers such as MST2, MHI2 or MHS2 help with classification but do not establish suitability on their own. We do not offer this activation for the described MIB2 devices without navigation and with only one SD slot.
Is a USB socket that charges the smartphone enough?
No. Charging does not confirm a data connection. A socket marked Charge Only is insufficient for smartphone connectivity. Depending on the device, suitable USB hardware with wiring and coding may be required. Activation does not replace these hardware modifications.
Does my system need an update or coding first?
Any required firmware update is assessed separately from activation. Premium sound systems require a separate check of the update path. Audi may also require OBD2 coding or activation of the Green Engineering menu; the individual check and instructions clarify the specific scope.
Can I add Apple CarPlay or carry out a retrofit with this service?
On a suitable existing MIB2 system, activation can enable the smartphone function already supported by the hardware and software. A retrofit involving hardware changes, installation of a new radio or a missing USB data port is not included in this service. The MIB2 solutions described here start with wired use; wireless functionality is not promised.
Can I have the vehicle's voice control activated?
If voice control is not yet activated in your vehicle, we enable it at no extra charge as part of the checked activation for Apple CarPlay or Android Auto.
This addition is part of the individually checked smartphone activation. It does not imply a blanket commitment for every vehicle.

Make, model or software prefix alone does not establish suitability. The complete version information, vehicle details and USB equipment are decisive. Use the compatibility check before ordering.
