I had problem with my Vivaro CD30 Mp3 Aux when it got wet inside and shorted out so have purchased a second hand CD30 (No MP3) complete with paired display out of a corsa from a local electronics shop.

The radio works perfectly except it is not back lit and the display does not show the temperature.

If I refit refit my old display then the temperature shows but as it's not paired tou just have the 'safe' warning on screen so is useless.

I have spoken to the shop I got it from and he says it is a common problem and the only way round it buy a new head unit and display from Vaux.

Can anyone help?

Cheers
