1490LMT wants me to take local routes instead of hwy?

Do you have Avoidances ENABLED? If so, whats is set to avoid.

Turn Eco-Route OFF. It thinks anything over 40 mph is bad.

avoidances are all disabled.

i am not using ecoroute for routing. (i just use it to calc MPG.)

my gps is set to Fastest Time.

do you have avoid traffic turned on?

Sometimes the 1490 will see highways as being congested and route you across local streets.

I've had the 1490 (on a cross country trip) take me off of an interstate across city streets then back onto the interstate only to find out I'd been routed around a congested area (in this case it was construction).

"do you have avoid traffic turned on?"

no, its off.

when i had the 255w, i found the traffic rerouting to be worthless.

Strange routing indeed. Not sure why it is having so much trouble, but a search should reveal a lot of people reporting their Garmins giving strange routings for no apparent reason.

To force the unit to route the way I want I'll sometimes add a waypoint to use as a via. Other times I'll just let the unit keep recalculating until it figures out the correct route. One shouldn't have to do this, but its pretty common for some reason.

The only suggestion I can make is these navigation devices are for assistance only. One should always check to make sure it is routing you where you want to go the way you want to get there before one puts the car into drive.

That won't help with the weird routes it sometimes comes up with, but it will help keep you from following silly directions.

For troubleshooting purposes, go into the avoidance screen and UNCHECK ALL possible options. This will rule out the issue is avoidance related.

I agree a double check is warranted since that's the most common cause of odd routing although the poster has already stated that all avoidances are already off.

I wonder if the use of eco-route to compute mpg might be the culprit. What would happen to routing if eco-route were fully disabled on the 1490LMT?

Using fastest time, when I get a very lame routing instruction, I ignore it. When Jill notices, she says, "You missed the turn" then upon recalulating, the new ETA is a few minutes sooner.

On my 2460LMT iI have both Eco-Route and Traffic Trends disabled, I've read they can slow down the unit and cause problems. I personally have no need for them. Good idea to disable and rule that feature out as a possible cause.

My NUVI40 does the same. I thing it is because it has no concept of lights and traffic. Point-to-point, allowing only for road miles and speed limits, it may indeed be the fastest.

Sounds like a lazily written algorithm. Node and vector math is hard.

yes, everything was unchecked when i started my trip

So we can rule out avoidances.

Was Eco-Route enabled when you took the trip?

One time I was getting some crazy routing when trying to plan a trip. I thought I had checked everything and couldn't find anything wrong in my preferences. It was so screwed up that the nuvi was even taking me the wrong way on a 1 way street! Then I felt really stupid when I realized I had left it in Pedestrian usage mode from the last time I used it while walking in a city.

Looks like the Nuvi was set to automobile so that's not the culprit.

Still need a reply from EcoRoute1 regarding if EcoRoute was enabled when making the trip.
If yes, perhaps disable it and do a simulation test to see if the route works properly.

Since you state that you just updated your maps there's a good chance that your firmware was also automatically updated during the process.

I recommended you do a hard reset which has solved similar problems for others in the past.

Good luck

i know i've seen the ecoroute routing setting, but for the life of me i cant find it anymore?

will doing a hard reset kill the connection to my ecoroute hd? it was a bitch getting my 1490 to find it. i still dont know how i got it to connect finally

Other than a hard reset?

My NUVI40 has no EcoRoute, all avoidance's turned off, and it still does that. Think it is just that Garmin picks the first route it computes, and goes no farther.

this unit is a dismal failure and the worst POS GPS I have ever owned. The routing is simply abysmal...I have MANY TIMES experienced exactly what you describe and no amount of futzing has ever cured it. PLease, if you can, take the 1490 back and choose another unit...mine is so bad I will never buy another Garmin and can't wait for it to finally die to replace it (I cannot abide wasting money). In addition, wait for the spasmatic reboots and forget trying to update maps, the internal memory is way too small (cured, admittedly, with an SD card).

Find another unit!

I was recently in Rockville, MD and had to drive back to Old Towne Alexandria during rush-hour. The Garmin routed me directly through Washington, DC with a million stop lights and lots of traffic, while Google Maps and Navigator on my Android phone routed me south on Washington's Inner Loop, which was was opposite the traffic, and along the George Washington Memorial Parkway (again opposite traffic) straight into Alexandria.

I kept the Garmin on while following my phone's turn-by-turn instructions(free on Android), and it kept trying to route me onto surface streets.

From now on I am going to use my phone's GPS. Garmin's future is bleak.

yep this is weird

I use to live just outside DC. What is the Inner Loop?

Maybe not. Garmin cannot store data for all stop lights, so it cannot take those into consideration.

Same thing.
Using my Nuvi 765T w/latest maps & firmware, & just ferries avoided, it tried to route me off the SI expressway right after Victory Blvd, and every other exit until I took the lower level on the VB.

I495 makes a loop around DC, so I believe the Inner Loop is the clockwise flowing part of I495.

Oh, I just call that the Beltway.

I guess both lanes combined is the beltway, made up of the outer loop and inner loop.

Either way, I try to avoid this area as much as possible.

funny thing is my 255w never rerouted to local to goto the verazono. but it only had 2012.30 maps.

maybe its the 2013.10 map thats the problem?

If you avoid the times that people go to work and go home from work, it's not bad.

If you think the Beltway is bad, try the Shirley Highway during rush hours. I drove it twice daily for four years.

My 13xx and 14xx routing got screwy with 2012 map update. I was hoping that 2013 map would correct that. I guess not.

My 1490t selected an approx 300 mile route to home which was neither the fastest nor the shortest. My 295w with a 2012.10 map, chose a route that was quicker and shorter than the 1490.

I have been using the 1490 for over two years and have never experienced any of the numerous 1490 problems listed on this site. I have never updated the maps. I wonder if I am just one of a lucky few or is this thing about to self destruct on my dash...cz

My new 2595 with updated 2013.10 maps and 6.60 firmware behaved strangely trying a route from the NY Container Terminal to Brooklyn. Told me to get off I-278 at the MLK, over to Clove Lakes, then back to I-278. It worked fine with the same firmware and 2012.20 maps.

After updating to the 7.10 firmware yesterday, the 2595 now chooses the I-278 Belt Parkway route straight from NJ to Brooklyn.

So (for me at least) the problem was fixed by the firmware update...

firmware update for all models or just yours?

The firmware I posted about was for the 24x5/25x5/34xx/35xx models. I don't have a 1490 any more, so I don't know if there is an update for yours.

For my GPS,the I-278 Belt Parkway routing problem seemed to be a combination of maps and firmware. The older firmware worked with 2012.20 maps but not 2013.10. The same 2013.10 map works fine with the latest firmware released Monday (7/23).

Maybe the 2013.20 map (in August?) will fix this problem...

I had these same issues straight out of the box. Especially the spontanious rebooting.

It turns out that the USB jack on the back of the unit was defective. Why it keeps rebooting is because the USB jack in the back is defective, and the unit can't maintain 12v pwr. If the unit can't detect 12 v pwr, but can detect a USB is connected, then it thinks it should go to mass USB storage mode.

I'll bet, as with the one I HAD, you'll find that it works just fine without 12vp.

Well, anyhow, I did a return, and selected a model one down, 1450lm. Wala, no issues. Like my 1450lm very much.

I responded to your other thread with the following Garmin response, but in case you missed it, here it is again:
(FYI: I also tried reintalling the latest 765T firmware a/o a couple of weeks ago, it didn't help).

Since I posted last, I sent a note to garmin Cartography about this issue and their reponse is pasted below:

Good afternoon,

I have an idea or two from my part in the investigation—from looking at the different map versions and some different buried attribution between the versions. My thoughts may or may not hold water in the end, but all appropriate parties are looking into it deeply now thanks to your mentioning it.

Best regards,

on trips up and down I-95 in Maryland. The 1490 does not like to stay on the actual highway, it wants to take the service roads. It is very annoying.

I have seen this routing problem on my nuvi 3590. While coming back to Santa Fe from Albuquerque on I-25 I had programmed my nuvi to go to a WalMart in Santa Fe. It tried to tell me to get off the highway onto a frontage road several exits before it should have, with several stop signs. It tried to do the same again (onto the same frontage road) at the next incorrect exit. Funny thing is that the frontage road eventually merges onto the same road that the correct exit takes me.

All avoidances are unchecked and fastest route is selected.

Where I live we have a highway going across the city which has up to 6 lanes in each direction for about 25 miles. Three lanes are express with very few exits and the other 3 have frequent exits. My 3790LMT wants me to go in the lanes with frequent exits even though I go from one end of the city to the other. Set for fastest route too.
The 3790 is supposed to learn your traffic patterns by the way you utilize the routes you normally take. Maybe a slow learner!

Is the 1490 supposed to learn too?

Here's the latest excerpt from my communication with Garmin regarding being routed off the Staten Island Expressway onto local routes for no reason (I may re-post this in other related threads):

We have the data which will be 2013.30 hosted now, and it has the attribution change I talked about before which changed routing behavior.

I just gave its early, rough self a test next to 2013.20 to be sure. What will make up 2013.30 does behave differently/better.

What makes up 2013.20 is the same there as 2013.10.

Even if I had caught my error, it couldn’t have been changed in time to get into 2013.20. By then, all of it was already in the hands of the paperwork gods.

Too many mapping windows & programs & versions open at once…

I have a 1690 and once it wanted to re-route me off the I-17 freeway heading into Phoenix. It showed me getting off, going down a road and back onto the freeway, except the re-route would have taken me 50 miles around the freeway to avoid some highway work for about 1/4 mile. Sometimes you just have to know that the GPS is wrong. I never use the re-route function.

My 2460 (LMT, current on firmware and maps) insists on taking me through the Haunted Forest if I use it to visit a friend down in Morgan Hill, South of us.

The road he's on is paved for a few miles, up to his house and about 300 yards further. Then it's unpaved for about 1.4 miles THROUGH THE HAUNTED FOREST where it exits on to a larger (paved) road.

The maps must think it's a paved road all the way -- avoid unpaved roads is indeed turned on.

Routing thinks it would be quicker for me to go through the Haunted Forest...

I think it's in cahoots with the critters in the Haunted Forest who want to gnaw on my bones...

Sounds like it would be a good place to put a custom avoid.

Not sure if mentioned by hard/master reset probably loses Favorites, pre-programmed routes (if model has that), and more so you need to copy current.gpx to computer before reset and copy it back afterward.

I too drive from Rockville to Alexandria a lot and it always routes me on the inner loop.

I'm using a 1450 LMT
