Skoda Karoq Audio System Failure

I had a similar problem with my Skoda Karoq. No audio and navigation issues. It could indeed be a MOST bus fault. Check the control units connected to the bus system.

Did you also have to replace a control unit, or was it a fiber optics issue?

Yes, in my case, a control unit had failed. The workshop diagnosed it quickly. They checked the fiber optics, but the control unit was the culprit. I suggest visiting a workshop.

Thanks for the information. I took the Karoq to the workshop. As suspected, a faulty control unit in the MOST bus system was the cause. The fiber optics were checked. Repair including the control unit replacement was around 1000€.
