I doubt your wedge boxes are the right ones. I don't believe they start delivering '09 planters until later this fall. One quick qay to tell is if you hook up your GS2 and the GS1 screen is no longer needed to run the planter. I haven't done this yet, but our dealer is positive that it won't be that way.

If your dealership is willing to swap for free you have a good one. Ours doesn't even know what the price for the swap will be yet. Might be a few hundred $ might be over $1000.
