UPDATE - POSSIBLE WORK-AROUND
Before reading the update, here are a few tidbits:
1. The issue comes when its cold. This is confirmed by DT RAM 1500 and JL Jeep Wrangler owners.
2. The only way for it to "reset", is to:
a. Wait for the truck to sit for 30mins+ (giving uConnect to restart from boot - you know when you get the "warning" splash screen with the "accept" button to skip".
b. Disconnect the negative terminal on the battery or pull the radio fuse - this also makes you have to go through a few procedures in order to get your settings back (after connecting the battery and starting the truck, shutdown the truck and close the door, then restart the truck, voila your theme settings among other things are back).
So we all know the issue returned when the temperatures dropped. This completely rules out a software issue, as software isn't affected by temperature (unless something is programmed). So none of the current software TSB's will fix this. There is a theory on the rear camera causing the issue, but part numbers between RAM 1500s and Jeep Wranglers are different, where the Jeep's camera saw a revision in part numbers. There is also a factor of common programming between the cameras (regardless of hardware part numbers), or bad wiring, possibly causing this issue.
Thinking about temperature, what do our trucks do when the temperature drops to a certain threshold? They tend to rev higher at startup-idle, and I'm sure a circuit or two must open or close somewhere to make that happen, among other things to get these engines to start in cold weather. Also thinking about what most of us do when we start our trucks in the cold - we crank the heat. But what happens when we're done our drive from point A to B? Usually the heat isn't cranked that high anymore, probably set at low or medium heat to maintain a comfortable temperature.
So I've been testing this theory for the past 2 weeks. BEFORE you shut down your truck, set the heat to the highest setting. So in my 8.4" Nav uConnect, I have dual zone climate control. I set both (set at sync, so they change together) to *HI* before shutting down the truck. So far, given the weather in Autumn weather in Toronto, Canada (about 2-3*C in the morning, reaching about 9-10* in the afternoon) the issue hasn't returned.
I'm asking everyone with this issue to try this - if we all can concur then we have a better basis of figuring out the issue, seeing that FCA/RAM doesn't seem to be resolving this issue for us - even after one year.
TL;DR - set the heat to the HIGHEST setting (both if you have dual-zone climate control) in your truck *** BEFORE *** shutting down your truck. Report back if it comes back.
