Fitting stereos to MK4s is a ballache, To get room for the wiring loom, I cut the bottom drawer in half and covering the end in black tape so it looked normal in the car.
You've blown the "S Signal" fuse - the location's in the manual. If I remember correctly, its a 5 amp mini blade fuse.

Keep trying combinations with the wires, you'll get there. I know its a nightmare as its happened to me on many occasions. On some cars, you only need one wire connected but I'm sure thats for permanent on wiring only.
Oh and if you use the radio, get an aerial amplifier now so you don't have to take the stereo out again. These are £10 from Halfords.
