VY Cluster definitions of levels

[1_johnboy]

I`m looking at putting a higher spec cluster in my VY S. Just wanting more options. I have looked around and have seen vy berlina/calais cluster and some have level 2 and level 3 and some times "standard" on them - Yet both look the same and are 3 window clusters.

I have now seen a level 4 from a statesman (visually different) larger round "extra" lcd screen.

My questions is what is the differances between the levels and different options.

Also wanting to know how to tell the differance between series 1 and 2 clusters ( is it just the plug color, or a part number I should be looking for?)
