I would really like to know whether he's talking about regular SPD's or the SPD-SL's. But OP is MIA, and people are falling all over each other to try to help. Soon the arguments between the various helpers will start. An all-too-common occurrence at BF these days.
My pet theory is that the mods start these threads about really basic subjects, in order to increase site traffic, but hopefully I'm wrong about that.
