Excellent! So great to hear another success story. seems like the Chrysler maintenance team are the only ones that have yet to figure this out.

I think the idea is that replacing the entire radio will be a “proper” and permanent fix to the issue of memory corruption of the detailed map data, however it’s not guaranteed since the replacement unit could fail in the same way. reflashing the map data will fix your problem, until it gets corrupted again. I had to flash it once... hasn’t been a problem since. If it ever gets corrupted again, I will follow the same procedure using the map data I already have to restore the maps. seems like that is the best approach.

The original repair was for a transmission side axle seal leak.

It’s not an issue of the nut having come loose. It was never installed when the shop was putting it back together after the CV joint repair. If the nut had been installed and come loose, it would have been caught and rattling around in the alloy wheel wheel hub... from what I can tell, this nut isn't what holds the wheel on, but seems to only pull the CV axle out and hold it in place. If this is correct, the purpose is to make sure the CV axel stays engaged with the wheel hub to provide drive force to the wheel. I’m not sure how the drive force is working without the axle nut.

So I had my 2015 Journey in to service a leaking CV axle joint a few months ago and to my surprise when I was swapping out my summer tires for the steel rim winters today I found that there is no CV axle nut on the shaft they worked on. Any thoughts on how that might have happen and what sort of risk or damage the vehicle might be subjected to when driving for a few months with no CV axle nut?

Same result for me! Nav has been restored.

I’m in the same boat now... will be ordering the updated maps and hoping it restores my Nav functionality. FCA had suggested they would cover the cost of the radio replacement if a dealership diagnosis indicated that the failure was related to R65. The problem is that there is no diagnostic that the dealership can perform that would indicate this. All their $140 diagnostic fee is able to determine is that the navigation is not functioning. There is no way for them to determine why. Since their ability to troubleshoot is limited to flashing the software (not maps), once that is complete the only course of action is to charge the customer to replace the entire radio unit.

I assume you followed all the steps laid out in the upgrade instructions found here... https://chryslergroup.navigation.com/web/WFS/Shop-ChryslerNA-Site/en_US/-/CAD/ViewProductAttachment-OpenFile?LocaleId=en_US&DirectoryPath=ChryslerNA&FileName=CTP+RB5+User+Guide+2019+New.pdf&UnitName=Shop

I wonder what happens to the update if the data it needs to pull from the target is corrupted?

You mention a “donor DJ”. Was your radio hardware previously replaced ? I’m wondering how the map licensing works and concerned that I might have an issue since my current data is corrupted. The “user guide” that comes with the updated map USB seems to indicate that you need to successfully extract some data for the upgrade to work.

Navi/maps issue only for me... everything else works fine.

Here is what it looks like for us Canadian folk...

My experience has been incredibly challenging and frustrating. Unfortunately due to the incompetence of the dealership I went to for the required “diagnosis”, FCA will not cover the cost of replacement. Based on the language FCA used it did seem like if the dealership had indicated that my failure was related to R65 they would have covered it. The service manager at the dealership I happened to go to claimed he knew nothing about R65 and that is wasn’t up to him to decide whether FCA would provide warranty coverage on a failure that would otherwise be considered out of warranty. No amount of discussion could get him to budge and so his “diagnosis” and feedback to FCA was that my failure was not related to R65. My my next step is to try with another dealership but FCA might not be willing to reopen the case even if I can get a dealership to recognize my navigation failure as the type identified in R65. Is is there any chance my “can’t unlock maps” error is due to anything other than the memory corruption documented in R65? All I got back from the incompetent service manager was that the navigation has failed and the only option to restore it is to replace the radio. If I can’t get FCA to step up I will probably buy the updated maps and flash to get my Nav back. (And also be left with a bad memory of my experience at this dealership that will result in me advising as many people as I can to steer clear.)

This thread has been very helpful! Unfortunately my Chrysler service manager has not been ... I took my 2015 journey with the “can’t unlock maps” error in for “diagnosis” based on guidance from FCA Canada and after charging me $130 he determined that the radio navigation was “broken” and the radio would need to be replaced. He couldn’t tell me what was wrong, but he was absolutely certain that it wasn’t related to any warranty coverage or campaign. I got the impression he had no idea what R65 was and he wasn’t interested in reading the notice which I had printed out. His final position was that I would need to pay $1000 plus one hour of labor plus the diagnostic fee to restore the navigation and that it wasn’t his call to determine whether the work should be covered as a warranty item under R65. Also, not entirely sure what the $130 “diagnostic” fee got me... me to service manager...”my navigation is not working and I think my radio needs to be replaced”. 4 hours later... service manager to me... “your navigation is not working and your radio will need to be replaced. That will be $130”. totally frustrating waste of time and money.
