No solutions on my end, but I should say that my problem came completely on its own. No firmware downgrades were done prior. I'm basically in a position where my compass, navigation, and auto clock set no longer work.

I forgot to mention that the first thing I tried (when flashing Garmin updates) was the latest available on the UConnect website. That also ran into the same "0x31A0" error code.

The problem is that original dealer where I bought the car replaced the head unit when I bought the car. So, they know it was working. As for the other dealer where I had the battery replaced, they were performing all of my open recalls and doing a full inspection. So, they know it was working as well. So, I'm SOL. I'll continue to try to flash Garmin updates, but I'm sure I'm running into the whole flash drive pickiness problem that I've seen on this and other Dodge forums (considering I've tried three different flash drive brands/models).

Any attempts to either flash the latest Garmin update (on the UConnect website) or to downgrade to CTP13 via recovery (under the Dealer menu) results in "Error on Reflashing. Errorcode: 0x 31A0. Please touch screen."

Ok, just reconnected the negative and it made no improvement in any of the issues that I mentioned above (black screen for nav, no compass, and no clock auto set). Reflashing UConnect "16/21/D7" didn't help either...

I just pulled the negative (once I went to the store and picked up a 15mm socket) and will definitely wait at least 40min before reconnecting. I should have mentioned earlier (before you replied) that I did trick the radio into reboot by going into dealer mode and hitting "restore user settings". It basically errored-out and then prompted for a reboot. Unfortunately, once it came back up, all GPS functions seemed to stop working, including the auto clock set and the compass (which just displays "--" now). Nav was still showing a black screen as well... So, hopefully, me pulling the negative will fix all of that.

I have to double-check, but its at least $300. - At the moment, with my finances, that's an expense I would rather avoid. Thankfully, it's not a critical function and the Journey would still be drivable without it. - It's just an annoyance more than anything else.

Nevermind. I should have looked this up before I opened my mouth (lol)... I just pulled this pic from a YouTube video.

The battery was already replaced in August. - For my particular model/year, it is located in the front bumper below the headlight housing. I know that there is a positive terminal under the hood, but I haven't seen one for the negative. Does that still apply to my model/year?

Rather than resurrecting one of the older threads, I figured I would start a new one. I've had my Journey for about three years (2nd owner), in which the radio unit was replaced within the first month through CarMax (the navigation wasn't working at the time). Since then, the system has been running fine. However, I just noticed today that the navigation screen is completely black/blank. Going into the dealer mode doesn't seem to provide any info either. - I tried any of the methods I could find to either get into the engineering menu or preform a soft reboot, but neither were successful (meaning I couldn't get into the menu or even do the reset). I would like to try to get this fixed on my own since my warranty deductible is relatively high. -Thanks in advance.

@km-04, not yet. Holding off on doing any modifications until its warmer out.

Just got through swapping my dash speakers on my 2014 DJ (w/ 7-speaker Alpine) to the 3.5" JBL GX302, which made a huge improvement in the Highs. However, (as to be expected) my system is currently unbalanced and does not have enough bass. At the moment, I am going to keep the system stock, avoid adding an aftermarket amp into the mix, or a separate sub. With that being said, does anyone have recommendations on a good set of 2ohm speakers for the front and rear doors? I want to avoid going with a 4ohm set and cutting the power output in half. I was considering getting two sets of the JBL GX963 6x9" 3-way speakers since I can get a refurbished pair for about $60 on Amazon (knowing that the front doors only receive a mid-range/mid-bass signal). However, I've read some mixed reviews from other Dodge owners with similar Alpine systems.

Sunroof issue was fixed after the replacement. Picked my DJ on Friday, and had no issues since.

Spoke with the dealer just now, and was advised that they did find a fault in the sunroof module. Apparently, its part of the motor assembly, and not a part that can be individually replaced. Thankfully, its being covered under the 30-day policy, and does not require a warranty deductible. Once they receive the part and install it (later this week), I'll update the thread.

Thanks @jkeaton, I tried searching the forum earlier, but didn't use "fog lights" in my search terms.
