I just had to open my dash up compleetly today to get my empeg out of the sled... It was stuck in there good enough so that I thought I would break the handle if I tried pulling on it any more. Sure enough, when i finally took the sled out and wedged the screw driver in the right place, the docking connector only had one screw in it. This was my backup that i'd only been using for two weeks and the other screw was loose, so it probably was loose to start out with.

Check and make sure that the screws themselves are tight, even though the connector moves... Otherwise be prepared to have to open your dash up to fix the problem...
