Initially, I had a friend at my dealership remove component protection. Since my car already has AppConnect and the appropriate FEC, it was easy to retrieve. However, he was not able to get Voice Commands and Bluetooth working. I had to enlist "Jack" for those to function. The 2018/2019 S/Rabbit radio does not have nor require FEC's for those options, but MIB2 does. If you search my name in the original MIB2 swap thread, written by George Ab, you'll read more about the issues I originally had with FEC's and Component Protection.
