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...

Joke reference:

The holy battery reset: Thou shou disconnect the negative terminal and wait till 30 minute. Not 31minutes, nor 29 minutes unless thou shall immediately continue onto 30 minutes.

In all seriousness, disconnect the negative terminal under the hood by the driver's strut. It's a 15mm bolt. let it sit 30 to 40 minutes. Then plug it back in. If the screen works again, but then a week later acts up,  then maybe you're looking at a new battery or at WORST a rebuilt alternator in the next few months. Additional issues that may arise soon are the dash lights flicker, the low-fob-battery warning, and the comical yet annoying wiper blade going, the outside temp reading -40,  among many things. These are just the dodge's friendly way of saying the battery might be going bad. 

 

Good luck!

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.

just wondering what you consider high for a ded ? hope you can fix this yourself seems once they start having problems with the nav it becomes a head ache to figure out,i am sure there are some on here who can help you ,might take a while for them to see your post so be prepared for a couple of days to see some help

 

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.

Was curious if anyone has looked into LEDs for the rear bumper reflectors on the DJ, and if anyone thinks it will interfere with Canbus...

@OhareFred, I was thinking along the same train of thought about the memory issue and a possible module. As for the question about it working if I start it right away, I want to say that it does work in that instance, but would have to test again.  I know for a fact that it does not work if ts been off for a while, or if you wait for the car to turn completely off (dash and info panel are off, etc).

I'm pushing for the dealer (non-Dodge) to fix it since it was not resolved when I last brought it back in (especially as I am still in the 30-day period). All they did the last time was initialize it.

Thanks @HugoClement, I'll definitely keep that in mind once I get my light kit ordered and shipped.

@OhareFred, just trying to get an understanding what would cause my issue or the need to go through the learn procedure for the sunroof multiple times. I've only had the vehicle for just under a month, and not fully familiar with everything to say what is exactly at fault.

As mentioned in the OP, the sunroof forgets how to work properly everytime i turn off the ignition and leave the vehicle (fully off). From there, the next time i get into the vehicle none of the buttons work with the exception of Close. Holding that button down twice starts the initializion/learn procedure. After that, the sunroof will function correctly until the next power off.

Didn't even know sunroofs had memory.....

Its only the conclusion that I can come up with.  I just know that Dodge vehicles have initialization procedures for their sunroofs, and is sometimes needed after the battery has been disconnected. Just don't know what maintains the sunroof's status so that you do not have redo the learn/initialization procedure every single time the vehicle has been completely turned off.

I have a 2014 Journey Limited (purchased last month), where the sunroof does not seem to retain its memory. So far, for the past two days, I have had to re-initialize the sunroof to get it to function again, including venting.  Now, I am not sure if this is a matter of me not having the complete/full initialization process, or if a fuse has gone bad (can't find any reference in the owner's manual).

What I have done is test the open and vent buttons (the rear two on the panel), and verify if they are working or not.  If not working, I will press and hold the close button until the sunroof goes into Vent mode.  From there, I will press and hold the close button again until it has fully cycled (full open, to full close, back to vent), and will continue to repeat this procedure until the close button no longer does this (and the other two buttons work).  Once that is done, the sunroof will operate correctly until the vehicle has been completely turned off (ignition off, touchscreen off, dash illumination off).

Does anyone know what is responsible for the sunroof's memory?

Guys, I have a 2014 AWD Limited (purchased last month) w/o stock footwell lights, and was looking to add an aftermarket LED set (not purchased yet). The goal is to have illumination either when the doors are opened or when the dome lights are activated. However, I'm not sure where would be the easiest location to tap into the wiring for trigger.

Any suggestions?
