DAB radio in my car stopped working and it costs £650 to fix. The service guys said they have to replace the whole centre console. As I won't pay that much, it's FM radio or Bluetooth for me.
To be fair, that's usually the only solution official dealerships know. When the CD drive stopped working in my LR Discovery 3, the garage quoted me almost £1000 for replacing the whole unit. I took it to an electronics repair shop, who took it apart, replaced something inside, and ended up charging me £100 for the whole repair.
