Specialist expertise.
And here for you.
Welcome to ProTech Schrötter. We specialise in vehicle-specific digital activations of App-Connect, Full Link, SmartLink and Audi Smartphone Interface, as well as vehicle coding.
We first check what your system supports. You then receive suitable instructions and personal help via WhatsApp message if you have questions. This contact remains available after activation.
Personal activation in Hanover
We offer digital services and prepared SD cards throughout Germany. For personal appointments, we operate as a mobile service in the Hanover area: we do not have a shop for customer visits and arrange a fixed meeting point with you. This saves ongoing premises costs and helps us offer services at affordable prices. We first use your vehicle details to assess whether the requested activation is an option for your system.
To request an appointment, simply write to us via WhatsApp or email. Please give the vehicle model, year, infotainment system and desired function. We will respond with an assessment and discuss a possible appointment.
