disc button not working Yaris 2008

[YarisB]

Hi all,

I have a Yaris of 2008 with the default radio/cd player in it. However, my DISC button doesn't do anything. It doesn't do anything via the console or the button on the steering wheel. I bought a cable to give me a audio jack but I can't use it as the button won't work.

Is it possible to have the DISC button enabled? Is this something that a Toyota dealer can do?

Any workarounds for this? Somebody mentioned a Yatour/Mantson interface but would that work?

Thanks. Cheers.
