Hahahaha, yes! You seem to have added $6FL (USB) but not $644 (Bluetooth/phone prep). NOTE: $664 is USA spec Bluetooth/phone prep and $644 everywhere-else-spec, but nobody's really sure what the difference is, and all the retrofits (including mine) use $644.
Undo your changes to the radio (maybe it doesn't matter) then add $644 to your existing $6FL, reset, and you should be golden.
Certainly is interesting that you've managed to code the radio itself and turn the bluetooth option on manually, though!
