Hi, I got the new variation on the uv-5r (uv-5r ex). Trying to get it to program I kept getting "radio fail to respond". I discovered if you put pressure on the radio end of the cable you can read the radio. Evidently the jack is recessed a little more than on that model so it won't reach to make contact. You might can trim the connector back a bit and make it work. I'll try that next..73 Alan
