Hey, I've just bought a '96 Nissan Primeria with the standard Blaupunkt Head Unit. The only problem is that it needs the code put in it to work again. Now, I know what the code is, put have no idea how to actually enter it into the stereo. Nothing happens when I press any of the buttons. Probably a really simple fix but I'm pretty stuck 
Anyone got any ideas? I don't have an instruction manual.
