I have the same problem.
The GR300 bind flawlessly with my DX4s and its v1.0 firmware, but they won't bind with my new DX4c, which is kind of disappointing.
I suspect it is either Spektrum shutting the door on its DSM2 protocol, some flaw in OrangeRX implementation of the DSM2 protocol, or the AVC ready firmware that screws up the binding process with non DSMR receivers.
The DX4c is still pretty new so very little to be found on this subject.
