There are enough changes to the electricals/electronics that I would be quite surprised if you did get it to work with what you say you have.
If I'm right the updated dash needs the BCM (Body Control Module) to work, and the BCM will look for the matching PCM (Powertrain Control Module) and when it doesn't find it, you'll get all sorts of error codes - I believe there are three different computers in there, I don't remember what the third one is, that all have to be present, along with their associated sensors and actuators.
Good luck
