Hmm, now the question becomes do I wait for the software patch or take into the dealer. Over the weekend we went on a small local trip of about an hour in length. During that time, the system rebooted itself 9 times (3 of which before I even left the driveway). On the ride back, the nav system did something new. It calculated the route, then the map froze on one location. Still had access to all the buttons, I could switch back and for between media/radio/climate. Tried stopping the nav route and re-entering the route, it would freeze on the same location. Stopped the vehicle, shut it off, opened the door and allowed it to de-energize. Restarted the vehicle, system worked fine. Tonight, on my wife's 20 mile drive home it rebooted 3 times then as she pulled into the driveway, the screen went totally black. Nothing worked at all. Shut the vehicle off and restarted it. Works fine.
Now, should I wait software version 13.19 or take it to the dealer? Jeep Customer service called me this evening in response to the survey I had taken and that was their recommendation.
I really believe this is a software issue.
