Navigation Issues

Hi all -

I've been having some issues with my 2014 JGC recently. My NAV always seems to want to take me the long way, through local streets and such. I've been through all the settings but nothing sticks out. I recently compared a route with my sisters Lexus and her NAV estimated the trip at 38 minutes, where the Jeep estimated the trip to take 1 hour and 20 minutes. I'm running the latest version of the software, 14.05... I can't seem to figure this one out.

Re: Navigation Issues

Greetings,

I do not have the factory 2014 navigation. However, the first thing that I always have done with the various forms of navi, is to make sure in the route settings is set only to the FASTEST. I do not set anything for traffic detours or turn on the traffic. I include tolls as well. This how I test the functions to see how they work and establish base lines.

Hope this helps.

Best for now.

Re: Navigation Issues

^^^^^ What he said. You probably have it set to shortest route, which can take you on all sorts of side streets, etc.

Re: Navigation Issues

O.K. I had this problem for a long time and it was driving me crazy. I always had it set to 'Fastest' and it would take me down side streets, etc. (the scenic route) whenever I took a trip. I was using my iphone/google maps on it's little 4" screen. I was getting ready to fight with Chrysler for a refund on the NAV since it was worthless to me.

Now it seems to work perfectly!

The problem was the TMC avoidance was on for one or more items including traffic. You have to find this under nav/settings/guidance. There are a few settings that will reroute the jeep based on traffic, even if the traffic isn't really obvious. Once I turned those all off I regained control of my NAV.

This of course assumes you have this feature, otherwise see posts above.

Re: Navigation Issues

I've definitely play with the "Fastest" and "Shortest" settings with no luck. Aqua, I have a feeling this May be the cause, the NAV might be trying to avoid traffic and sending me all over the damn place. I'm going to test turning TMC avoidance off and post back in a little bit. Hope this is it!

I believe I have read somewhere in the forums that the navigation system is Garmin. The voice and commands sound like it to me. I have always been taken by a route I did not like when using a Garmin unit

Im not thrilled with the directions from my unit in my Mercedes either. The best nav I have had to date was in my'11 Nissan Rogue.

Re: Navigation Issues

The NAV unit does seem to need some work. Went to visit my daughter last weekend in Atlanta. I do not know my away around up there. It got me there ok but it took me on the scenic tour of downtown when we left. At one point it told me to turn left and as soon as I did it said it was recalculating and I needed to do a U turn so I could go back and keep going the way I was just going.

Re: Navigation Issues

Yeah, the navigation is a bit weird, but I've never had one before, so this is all new to me.

Once in a while, it wont lock onto me properly, so I will be going the wrong direction, at least according to the map. Very odd. I have to turn off the vehicle and turn it back on to get it to lock on. Can't just cancel the route and do it again.

It seems to happen the most when I'm trying to calculate a route while moving. But I've also had it happen when I was parked too.

This navigation system is certainly NOT Garmin. I have used every major Garmin release since they first had rudimentary maps on the GPS III and V and this is not it.

For me the worst of this is that when the autozoom is set to Far it still only shows about the next half mile. So I set it to Far when I need turn by turn directions and Off when I need to know if it is doing something sensible.

My experience over the years is that Garmin has been almost clairvoyant about arrival times, even half a day out. I used it to navigate from Alameda to Yellowstone, none stop, three drivers. It was only five minutes off when we left the house. Coming home is a 45 minutes to 65 minute trip, I can routinely take 20 minutes off the Jeep's estimate.

This looks much more like TomTom, but with less features. So I wouldn't be surprised to hear it's some East European software company, like the idiots Motorola used in their abortive foray in to GPS.

Re: Navigation Issues

Greetings,

I seriously doubt TomTom wrote this for Chrysler. TomTom uses their own maps which they brought form TeleAtlas a number of years ago. The maps in the OEM Uconnect system for the 2014 8.4 is from HERE, formally known as Navteq. Navteq has written GPS systems for various companies, like JVC aftermarket HU's. Garmin has a separate OEM division, so it could be them. Harman outsources their GPS systems with their own specifications to be built into the system.

Best for now.

I said it is like TomTom, it is always zoomed in too far to be useful. But it doesn't do as much as TomTom, so I doubt they are to blame. But it certainly isn't Garmin. Back in 2013 model year Chrysler was using Garmin and it was just like a decent Garmin unit with a bigger screen. I had it in three or four Alamo Chrysler 300s and a Durango if I remember correctly. The 2014 is not Garmin. It just isn't near as good as Garmin. The map display, route entry, and especially the auto zoom and ETA predictions, are just not near as good.

So it's now a Navteq system? Considering how long they have been making them this isn't particularly good. This is not a software A-team effort, I've been doing it for thirty years and I wouldn't be shipping customers the same faults year after year. By now they should be able to make decent ETA predictions and choose decent routes.

Greetings,

Funny thing, even back in the late 70's, you had the ability to make decent UI even though it was only a menu system. This was with the early microcomputers, mini's and mainframes. I clearly remember those days. Oh how I hated the punch cards with IBM's JCL. Moreover, audit control of the program was far better in that era, 80's, 90's as compared to today.

In any event, for a premium system in an vehicle like this, this GPS should be of a higher standard. Not something from yesterday. Algorithms today are far more advanced and the programmers should and must know how to use them. The real kicker is when they introduce advanced features, they never fully check to see if it interferes with something else. This is the biggest problem going on with these system. Show the bells and whistles and skip the hardcore problems.

I have noticed thru various different GPS systems including the apps, when they introduced the traffic scenario into the equation, the routing, time estimates, avoidance and etc... does not produce the right results. The real frustration for me, is when all these chooses are off and everything gets missed up.

Best for now.
