My 04 has the 60/40 seats with the driver's being connected to the annoying armrest / storage / flip up middle seat gizmo. If I recall correctly, the armrest is held in place with three screws at the back of the storage compartment. As for the lid / armrest, I think these can be purchased off Amazon or Ebay used and sometimes new for much less than a dealer OEM price.
I am not 100% familiar with the 2010 models so it may be different. I heard a rumor that the later models ditched the 60/40 with the console for buckets and a center consolette.
