Couple of days ago, for some unknown reason, my UConnect phone just simply stopped working. Couple of days farting around and reading a lot of internet crap and watching videos that said push volume and tune buttons where we have no tune button on a 2008. Anyway I just went to the garage turned on the stereo in accessory, pressed the iphone button and voiced "Pair A Phone" into it. Voice said enter a PIN (this confused me at first as I was going - what PIN?) so I simply invented a 4 digit PIN, radio asked if that was correct I said "Yes" then went to my Apple iPhone paired on Bluetooth and entered the same PIN and bingo it worked. So hopefully others can do the same. Radio is a 730N-RER model from a 2008 Rubicon.
