I have a 2007 JK 2dr that only had the 130 radio with no uconnect. I replaced the radio with a 730N RHR. Everything works great except for the mic. We had purchased 2 sets of mics thinking the first one was bad, but still having the same issue. We then took the radio and placed it in our 2013 JKU that already had the 730N worked great but plugged both mics in the radio, does not. However the mic that’s already on the JKU works. Is it possible that we need to do a flash? Or are we needing a different mic all together or needing more than just the mic?
