Figured I would share some input on this as I have been dealing with some uConnect issues since day one. I was the OP that installed the RAM update on my radio which worked out somewhat well (band aid untill the Jeep update came out back in May).
The original issue all started when I was getting the "phone requires service" message. No matter how many resets I could not get it resolved. Once I installed the RAM update it went away and did not come back. Had some issues with the RAM update but overall it was a small improvement worth doing while waiting for the Jeep update. Once the 13.15.4 update came out I installed that and it made the radio even better and more responsive.
Then some more issues came about, sometimes the radio would get frozen on one particular mode, not being able to change channels etc.. or would not get GPS Signal. While doing all the stuff with the RAM update, based on my relationship with the dealer, I was able to have them order a replacement radio and VOR it so I would get it ASAP. The units were on Backorder and it took a few days but we finally got it. At this point I was thinking to myself it was all just software bugs and I didnt really want to go through the hassle of having the radio changed. I figured why not wait for another update then see what happens but I was still having issues with my current radio on the 13.15.4 software. No voice commands, some freezing etc..
Then another issue popped up. After about 5-10 minutes of driving I would get "Blind Spot Monitor Unavailable, Service Required. I dont really use this feature and was in no rush to get it fixed but I reached out to the engineers I deal with at Chrysler and they said that I could all be radio related.
So sure enough this morning I'm in one of the service bays helping the tech replace the radio and for now all of the issues have gone away. The radio is still running the 13.15.4 software version. All the features are back and the radio seems much more stable, voice commands work, no GPS loss, and BSM is working as designed.
Interstingly enough, my previous radio was registered with uConnect access and worked great. I figured that when the replacement radio was put it I would have to Re-Register and set the service back up again, but no, not only was the radio already registered, but my app worked out of the gate and when I called the engineer he was able to load up all my data without me having to register again. Somehow these radios identify with the VIN # and when they are turned on for the first time they sync up with ChryCo servers based on VIN. This is why the radios have to be ordered for specific vehicles and the dealers cannot stock them. His system was showing both serial numbers and it was easy as 123.
The moral to this story is that as Willx and others like us are working on the software side some of your issues may also be hardware related. Chrysler is working to find out whats hardware and whats software so when your dealers send in a STAR case they can sort out a replacement radio for you ASAP.
Just my long winded $.02
