Did you bind the transmitter with the new receiver (2.4GHz
Multifunction Unit)?
Picture below showing the version of the transmitter I'm using that have smoke & volume button. I didn't buy the whole radio. I just get the transmitter board & 2.4GHz Multifunction Unit. I replaced the original FM transmitter in the radio with 2.4GHz transmitter. I forgot to take picture of the 2.4GHz Multifunction Unit board but I remember "2014" printed on it.
