Skoda Kamiq Audio System Failure
Summary of the thread
A 2023 Skoda Kamiq experienced a complete failure of its audio and navigation systems, with an error indicating a MOST bus fault. The MOST bus is a high-speed multimedia network in cars, often using fiber optics, where a single component failure can disrupt the entire system. The issue was diagnosed as a faulty control unit on the MOST bus, and after replacement at a workshop, the systems were restored to functionality.

Error codes are stored in the error memory. What exactly is a MOST bus? Is it related to fiber optics?

Yes, the MOST bus is a high-speed multimedia network used in cars, often employing fiber optics for data transmission. It's a bus network, a type of automotive protocol. If one component fails, it can disrupt the entire network. It's likely a workshop job to diagnose which unit is faulty.

I took the Kamiq to a local workshop. They confirmed a faulty control unit on the MOST bus. The repair cost was around 1000€, as predicted. The audio and navigation are working again. Thanks for the input.

MOST bus fault? Sounds like a headache. I had a similar issue with my old Volvo. No sound, navigation dead, the works. Is the car throwing any specific error codes?
