To anyone who's dealership says they don't need the update when you know that you do:

My car is 6100 something made in September of 03'... I work at a dealer... When the tech puts the VIN into TechConnect the update is not shown. Strange so we went to the tab that shows the build date and the field was empty.. We ran a VIN inquiry and low and behold there was no build date there either... I'm sure there must be other early crossfires missing the build date too.. Thus the reason for TechConnect not identifying the car as needing the update even though it DID.
