Thanks for all the suggestions, I will try pulling it out and wiggling the cables that might actually be the problem because of how I routed the new usb harness to go to the Head Unit. And if it did end up being the Head Unit, then its possible to have the FeC transferred so I would not have to pay for App Connect activation again?
Correct, you should not have to pay a second time for the App Connect FeC based on my experience. I did not have to pay a second time for the app connect FeC. I went with the same person who assisted with the original MIB1 to MIB2 conversion when I did the MIB2 head unit replacement. I paid $50US for CP removal and FeC reinstall.
