My Radio/lcd display is blank and I have been quoted a horrific price to replace with a new one part no 1640473 V70 D5 nov 2007. I have sourced a functioning unit which I propose to fit does anyone know if there are software issues required or if it is even possible to do this ? I have read various things where people have done it and say it works and others have said don't bother any help please ? I have hopefully included a photo of the part. Any help would be greatly appreciated.

Paul.
