Needed to post a followup on this thread for anyone that reads it in the future and wants to know what happened. The CPU that was installed was not defective in any way. The shop that installed the system had a few different CPU's on hand and installed one but gave the customer the serial number of a different unit he had ordered on the same order. Since the serial numbers were not valid the customer could not update the firmware. The original returned CPU was installed in another vehicle with the correct serial number and is working just fine. As a rule of thumb if you have a new install always verify the serial number on the bottom of the unit if you are having any issues updating.
