Help ..I've got a late 2003 406 executive (estate) and the display unit at the top of the centre consul that displays time/date/temp/MPG etc. has started breaking down into black lines across the screen and is now virtually unreadable also the remote control that changes date/time etc. has stopped working ..I don't know if it's the hand unit or the consul unit that is at fault (yes I have fitted new batteries) .. I have tried loads of breakers on the web. to buy a new unit with remote (easy to replace) but with no joy .. can any body suggest where I can buy them please??
