2460LMT really slow to calculate route

Mine did this once but I had all the eco stuff on and my routes were in 4 times. After I turned that off and deleted all the dup. stuff it works great again.

Strange thing is other than some POI's and a map update all my setting are the same as before it got real slow.

It was slower to calculate than my old 260, it may have to do with the traffic being included in the calculation but it was not even close to 15 minutes maybe 1½ minutes.

While in Miami I drove twice from the hotel near downtown to my brother's house, neither time it used the same route, Friday afternoon the traffic icon was red and it went city streets most of the way, today Sunday with green icon it went Hwy and Tpk. the whole time.

No real traffic to deal with though, it was Thanksgiving morning on the way up and the Saturday after on the way home. I've taken this route at least three times a year for many years, my wifes parents house for the holidays, but it took forever to load for some reason I have yet to figure out, never did that before.

Good thing I knew where I was going for the most part. I like to program the route for the estimated time of arrival.

On my 750 I could do a hold on button for several seconds and do a reset. I'm sure there is a reset on the 2460 but haven't found it yet. Maybe that would help.

Does anyone know how to do a reset on 2460?

Procedure for a hard reset for your unit can be found here http://www.poi-factory.com/node/32136

To perform a Master Reset on the nuvi 200, 205, 465, 500, 600, 700, 705, 1100, 1200, 1300, 1400, 1600, 2200, or 2300 series device

1.Start with the unit OFF and unplugged from power
2.Touch and hold the lower right corner of the screen with an index finger or the eraser end of a pencil
3.Continue touching and holding the lower right hand corner of the screen then power the unit ON
4.Release the power button when the device powers ON. You will see a new message: Do you really want to erase all user data?
5.Remove your finger from the touchscreen when this message displays
6.Touch Yes
The device will automatically reset. Follow the on screen prompts then place your device in an area with a clear view of the sky until it acquires satellites.

Note: A master reset will erase all waypoints or Favorites and will restore your unit to the default factory settings.

I assume the 2400 is the same as above??

Here s the link for the 2200/2300 and 2400 series so the hard reset procedure will work for your unit.

Thanks, and have a great week.

Just looked at this, it is very nice.

My 2460 unit calculates much quicker than my 1490. It gets a fix on sats much quicker too.

I just did a calculation of the route I mentioned, it took 28 minutes, then I did a hard rest and the same route calculated in less than 2 minutes.

WOW, wonder what settings I had that caused that much of a difference.

But it sounds as if it's a software error in the unit causing a "memory leak" where work spaces aren't being cleared and fill. The unit has to spend a lot of time thrashing through internal memory pulling fragmented data together. (And no, it's not the same as a 'fragmented storage' problem you defrag for.)

So does that mean the unit is defective? Do you think this will happen again?

It could be a software bug - and memory leaks are difficult to find at times.

Do you have the MyTrends feature enabled? I read on another forum that that feature caused excessive calculation times on the 37xx series, so it could be the same issue on your 2460. I think the Traffic Trends feature can also increase calculation times.

I think I did on both.

It has been my experience that having TrafficTrends turned on can cause very long route calculation times so I always turn it off.

I haven't found myTrends to cause any problem so for me it's matter of taste whether I keep it turned on or not.

Traffic Trend turned off. Alway want me to go a different route and recalcuation all the time.

With the 2012.1 maps my 1390 and 1490 both stall at 99% when calulating routes at certain places (Onancock VA). It might be map and location specific.

I too discovered after the last map update, my 2460LMT takes much longer to calculate the same routes that I've always used the GPS for. What used to be 10 or 15 secs, now is a full 90 secs and longer; The calculation progress bar sits at "0" forever, then slowly makes small increase, pauses, makes another small increase.

If I start driving before the route is finalized, it takes many minutes/appears to hang. The GPS signal is strong, and my location is accurate.

For what it's worth...

My is back to lightning fast after the hard reset and disabling the "trends" features.

Garmin has confirmed 4/5/12 that there is still an issue with the myTrends feature on the 2460LMT. Sometimes calculations take 15-20 minutes or more and virtually render the unit useless due to the myTrends traffic feature. If you turn off the traffic trends and my trends it is supposed to calculate much quicker. But then again what is the point of these great features on a higher end unit if they don't work! Garmin developers need to fix these bugS!

the Trends at all, especially the Traffic Trend. It want to send me on roads I don't want to be on.

I turned off Trends and a bunch of other "features" in an effort to narrow down why route calculation occasionally exceeded drive time...

Thanks for the verification; Trends stays turned off!

Think about the more you drive the bigger the “Trend” file will get and since the Nuvi is not a super computer it will slow down analyzing the origin and destination of all places you have been.

The fix maybe if Garmin limits the time period the unit looks back to establish the “Trend”

Where did you read that? Are they working on a fix?

.

My 2350LMT had very slow calculations and recalculations while in a route, I turned off the TrafficTrends and MyTrends, now the 2350LMT calculates and recalculates much faster.

Don't you just get sick of all the Garmin problems with there units? That is why I love my built in..in 5 years I have not had one single issue and it does 95% of what the garmin units do. What good are all the fancy features when they don't work properly. Then you can wait for Garmin for a year or more to fix the issues....I have a garmin which I rarely use anymore...my built in unit and phone do a much better job....just frustrating to me...

Appreciate the tips for speeding up the searches.

I have the 2460LMT with Trends on. The only quirk I found is if I'm not moving the unit will calculate a route very quickly. If I am moving and it is trying to calculate a route, it will take hours. If I come to a stop, it immediately calculates the route.

The other quirk, is If I am following a route, and deviate from it, the recalculation is almost immediate. It doesn't matter if I'm stationary.

On my 2350LMT, I have slow calculations or recalculations of a route while traveling, I found that if I turned off ecoRoute, I get major increase in performance when calculating a route, I went into Settings, Navigation, touch the symbol on the upper left corner of the screen, choose RESTORE, Restore the settings to the default values, choose YES, Now touch Tools, touch ecoRoute symbol, message now appears, You must set up your vehicle profile before using ecoRoute. Setup your vehicle profile now? choose NO,this will verify that echoRoute is no longer working, now test your GPS while traveling, I can now calculate a route from Illinois to Florida in 40 seconds, instead of 10-15 minutes at times while traveling. Hope this helps others with slow calculation or recalculation problems.

Yes - turning off Traffic Trends seems to have helped my calculation time too. Not tried a full restore yet, not found it necessary up to now.

Many thanks to those on this forum for the help.

Oh BTW, anyone know how to display Arrival Time, Distance Left, and Time Left all at once. I can "scroll thru" and dislay them singly, but not all together. I could do this with my Medion, but it seems the Garmin won't do it.

With a destination inputted on your Nuvi you can display 3 of many items on the map screen.

First go to Tools - Settings - Navigation - Automobile - Map Data Layout and select More Data and press Save.

Now enter a destination from Where To and when you see the map screen you'll notice that there are now 4 data fields along the right hand side of the screen. You can change any of those fields, other than the Speed field by tapping on the field icon and selecting an item from the list presented. That list includes:

Arrival Time
Distance
Time to Destination
Via Arrival
Distance to Via
Time to Via
Direction of Travel
Elevation
Time of Day

Just set each of the 3 fields to one of the ones you wish to have displayed.

Thanks t923347!
I'll try this out.
Maybe I can really tweak my Garmin so that it is 100% now

A couple of hours later......
just tried this and it works a treat!

Thanks a lot for the tip!

Thanks for the info

I suspect the 2595 may have this same issue with calculation time. I turned off traffic trends because I suspected it was causing the unit to build strange routes to destinations at times and which I had no desire to follow. I can't confirm this shortened the route calculation time, but my unit is much faster at this now and I assumed it was due to one the firmware upgrades. The traffic-trends feature may be nice in theory, but I think it needs more work.

do you think that the calculation time show be. I have a 2595LMT and it is fast enough for me. I guess the older you get time is not a factor.

At present, I think the calculation time is excellent. (It is -much- faster than my former 255W, which was no slug either.) However when I first got it, there were times when it was very slow and would hang for long periods when building routes. I believe a combination of firmware updates (3 since I purchased it in January), disabling traffic-trends and a couple of hard re-sets has corrected the problems I was seeing. I can also say I have seen/perceive major improvements to the search times for POIs and addresses and to the "searching near" interface. I also believe voice recognition and function has also improved with the new FW updates.

I been working with Garmin tech support regarding this slow route calculation problems, I sent the unit in for repair or replacement, the slow route calculation problems shouldn't be occurring Garmin said, and my device is still under warranty.

I discovered a SW/FW "anomoly" some time ago on my 2595. I was always puzzled why it was reporting fuel use and cost in the trip logs when I didn't have the optional Eco Route module. (and trying to set it up in "settings" would give the expected error message.) As it turned out, I discovered after a hard re-set, prompts to set up fuel type, fuel cost and gas mileage. I must have forgot about this after the first power up and set up. Once you enter the variables though and complete that initial set-up, there is no way to change them later.

So if you see fuel cost and use calculation on your 2595, that's the reason why. I would expect to see this go away in the future if Garmin discovers it and corrects it with a firmware update.

It is so frustrating that Garmin still doesn't have a fix for the MyTrends glitch. Turning it off helps improve calculation times but that isn't the answer!! What if this was a car... and your dealer said yea your engine will be fine as long as you don't use the air conditioning. If I buy a car with AC I want to use it!! MyTrends should work as advertised. I shouldn't need to disable features of the unit which are the reasons why folks buy the better more expensive units!! Like anything these days. Rushed to market too fast with bugs.

Here's an update on my calculation problems with a 2350LMT, I received my refurbished unit just the other day, everything working fine until I chosen a route while using the option PROMPTED in the CALCULATION MODE, now my GPS will not calculate correctly while the automobile is moving. If I choose FASTER TIME, no problems calculating while the automobile is moving. My version of software on the GPS is 3.50, I decided to check for updates on this GPS, new version 3.60 is released, then reading the 3.60 fixes, there's the fix for the slow calculation problems that I been having for sometime, fix for the PROMPTED calculation problems, I updated the GPS to 3.60, no more slow calculations with Avoidances, traffic trends, My Trends all turned on while using PROMPTED in CALCULATION MODE, Garmin tech support should have been notified of this software glitch, then I wouldn't of sent my GPS in for replacement.

When I first got the 2460, I tried the myTrends feature, but could not see that it was working so I turned off the feature. I was planning on turning it back on tomorrow but now that I read about the slow calculation problem, I'll just keep it off. I know that on my 1490T, I used the ecoRoute feature for months and that feature had caused problems. And when I deleted the data file for the ecoRoute, it resolved the problems on the 1490. So to sum up, I'll just use the garmins as a basic gps without the bells and whistles turned on

If you are the only person driving your vehicle and you never lend your PND to family members or friends the myTrends feature has to be the stupidest feature to have turned on.

All that myTrends feature does is remember how you like to go from point A to point B and unless you suffer a sudden Alzheimer attack while driving you already know how to get there.

On the other hand if you make it a habit of DUI it maybe a good feature to find home.

It did a great job of telling me how to get where my car could almost drive itself ...

I always thought the myTrends served two purposes. First, it "predicts" where you are going i.e. work every day leaving at 7:30 a.m. for example which although you obviously know how to get to work it can be helpful to show your ETA if you are delayed, or need to take a quick detour. Secondly, I thought the myTrends learns the preferred way you like to go so instead of routing you the way it wants to go to get to your favorite destination, it will say oh he likes to take the back road instead of the interstate or whatever and avoid the annoying recalculations and forcing you try to get back on the interstate. (I'm not too sure that it does a very good job of the second purpose as I typically go the same way every time and it still tells me to go through town when I go around my town to avoid lights and traffic thereby saving myself time. You would think it would realize that but I think the whole myTrends thing is weak at best - a nice thought Garmin but poorly executed.)

So... anybody know?

I had a similar experience with a new 2555 lmt
On a one point route - 'go home' the gps took a few minutes to calculate a route which suggested I go 130 km past my exit, turn around and come back

Reading these notes have helped
I have also sent Garmin a support request, but I expect to hear back in 'no time soon' with a solution, but it could happen, and they need to know.

I will turning Trends off, and then a hard reset.
Thanks to the collective community for documenting this

I just got this unit last week after having had my 750 stolen - it worked great and I had no need nor desire to replace it

The 2555 does have some nice features

When I get a new unit (2460lmt)I shut off all thinking (eco route,my trends Etc.)and allow for pure gps. The 2460 so far is superb. Then start allowing those options above one at a time to see if the unit starts acting differently.I'm still in pure gps mode because I can't believe it can get better. Did this with my 660,1490 and now this. 2013.10 maps and lastest updates. I did backup the unit. Eventually I play with additional setting out of curiosity but I'm sure I wont use them

It's the MyTrends feature that does it. Garmin even admitted it to me but it still irritates me that it doesn't work. You shouldn't have to disable advertised features and then wait a year or so for a bug fix. Ludicrous. Perhaps if Garmin didn't have so many different models to support, they could whip out firmware updates a lot quicker and be able to maintain current products better.
