I want to change my starting up logo from the opel badge to the vauxhall one but can't find the option to do it. I keep hearing something about entering "888888" but i dont know where to enter it. I have a D5123E unit so I know it has the option of doing it, I just can't find it 
Any one changed their or know how to do it?
(note: why don't they include this in the manual, would save a lot of hassle)
