CHR MOST Bus Audio Failure

Hey, I had something similar happen in my CHR! No tunes, sat nav dead...turned out to be a pain with the audio system. Does your infotainment screen work at all?

When you mention "audio system", what components were affected? Do you remember the error codes?

I didn't get the error codes, but the whole thing was dead. They said it was a control unit on the MOST bus, like you said. Honestly, I'd take it to a workshop. It's a tricky system to diagnose yourself.

Appreciate it. Sounds like a workshop visit is needed. I’ll post what happens. Repair is estimated around 1000€.
