8.4AN uconnect Nav problem 2014 Grand Cherokee

Hi All,

Got a 2014 GC Limited a month ago and recently started having Nav/ compass calibration issues on the 8.4AN taking it to the dealer tommorow.

Basically the Nav is consistently off by 100 miles or so and the compass points 180 degrees in the wrong direction, needless to say this is pissing me off . Does anyone else have these problems or have advice ? This just started happening this week. Everything else seems good so far ...

Re: 8.4AN uconnect Nav problem 2014 Grand Cherokee

<<UPDATE>> Like posted in the other thread Chrysler/Dealer is replacing the entire Head Unit !!!
8PM EST 04/24/2013

Question for Silver : are you in DC metro area by any chance ?

Symptoms :

"Phone Requires Service Message pops up"
"GPS Unit showing wrong location on NAV"
"Compass pointing in the wrong direction"

Am beginning to think could have saved 3K by not getting the friggin UConnect with Nav. Not that the Nav was very useful or responsive even when working ..

Re: 8.4AN uconnect Nav problem 2014 Grand Cherokee

I just had a problem with NAVI last night. At some point, driving on the interstate from the airport towards down town, the unit was off by as much as 200 ft (side streets) then after it corrected itself the map froze. The map could no longer be zoomed in/out and it would not move - soon I had gone out of the map area plotted on the screen. As I actually had NAVI guidance going, the VOICE continued to provide directions but the display in the dashboard also shut down.

I stopped the vehicle, restarted it but did not do the trick. At home I did the same thing, waiting 1-2 min before restarting, and the NAVI seemingly came back to life.

I am uncertain if there is a correlation between this and the fact that I activated UCONNECT the night before. There were no alerts on the dashboard.

Re: 8.4AN uconnect Nav problem 2014 Grand Cherokee

I saw a similar behavior during my test drive and the dealer told me that it takes some time for the system to calibrate (I found that very strange). If that is the case, you should not be having this issue after a month of ownership. Could be more to this issue...

My vehicle is working properly though...

Re: 8.4AN uconnect Nav problem 2014 Grand Cherokee

I drove the car this morning to a place to get it "tinted". The NAVI unit worked "phine" - not "fine" because it seemingly took longer to "activate". But it did its job as intended, as previously experienced, without any glitches - displays, alerts, traffic, routing and all.

Was using the nav to navigate to a house this morning. During the drive it said recalculating and showed me being on side streets off the highway. Turned the car off when i got to my destination, still didn't function properly, then 5 minutes later it started working again. No idea what happened, but this system does have some software bugs.

I hope everyone with problems is letting Chrysler know about them. That's the only way they will find out the software for the 8.4AN needs updated. Like with any software, be it auto, computer, cellphone, or what have you, it's always a work in progress.

Problem is its not a problem in their eyes if they can't see it happen, can't show em an intermittent issue.

Re: 8.4AN uconnect Nav problem 2014 Grand Cherokee

I was using navigation a few days ago, and the screen locked up. None of the controls(radio, climate, etc) would do anything. After I got home and shut if off, it was fine the next time I started it up.
