Laguna II radio display and remote both not working

Hello,



I have an 07 Laguna II Dynamique estate. The radio works but both the display (in the clock/temperature display on top of dash) and remote controls (on steering column) do not. I've tried another radio without success. The clock and temperature in the same display both work, but nothing is displayed from the radio. I've reseated the cables at the radio and at the display without success. I'd be surprised if both the display and the remote had failed. Does anyone have a circuit diagram for these items - do they share a common wire or fuse?



Any ideas much appreciated.



Thanks.
