new 765t shows home on wrong side of street?

 

Got a new 765t and it shows my home on the opposite side of the street. Has all the updates including maps. Everything else seems fine. I have a 360 and compared the two on a drive last night. Both have all the latest map and software updates. I also noticed the arrival times are about 2 minutes apart on a 10 mile drive to home and as I get closer the arrival time difference get less and less. When I get to home 765 says home on right (wrong) and the 360 says house on right (correct).
Took it on a trip to Vancouver BC over the weekend and it worked fine.

INCORRECT LOCATION

Have the same problem. I had to send an email to Navteq asking them to correct the problem. On there web site is a form you have to fill out. But, when will they do the correction is another problem. It will not appear overnight.

thanks

Maybe I'm opening a can of worms but why would the 360 show correct and 765t incorrect when both have the same maps or are the map updates different for each unit?

Address or location?

Have you set your "Home" to be your street address or have you chosen to select Home as your current location when your GPS is smack dab in the middle of your driveway?

When I first received my nuvi 750 with 2008 maps, the map's location of my street was slightly incorrect. When I chose my street address as Home, I got the "Home is on the wrong side of the street" directions, too. By selecting your current location as Home when parked in your driveway, my nuvi gave correct directions as to "Arriving at Home, on Left." Later map updates corrected the location of my street but I still use the driveway designation to determine where Home is.

Please check the version numbers of the map on both units. I have to believe they are different.

Nuvi 660 -- and not upgrading it or maps until Garmin fixes long-standing bugs/problems, and get maps to where they are much more current, AND corrected on a more timely basis when advised of mistakes.

MAPS

Both have 2010.20. The 765t has the 3d version also. If I sit in my drive way the 765t shows the house number as 15491 when it should be 15419. The 360 is right on. I went to navteq website and it also shows house on wrong side of street but then why would 360 show correctly and 765t not when they supposedly have the same maps?

check coordinates

Have you looked at the actual coordinates on both units when they are in the same location? That should verify that the received satellite signals and calculated positions are comparable. If the coordinates are within a few feet of each other, and if the maps are indeed the same version, then it would seem the error is in the software algorithm used to extrapolate addresses from the street map reference points.

Road lock should minimize this problem

One would think the logic that tends to lock your vehicle icon onto roads would also result in it accurately telling you on which side of the locked-on road the destination is.

Maybe the two don't know about each other?

I have asked Garmin about this too because it seems to me like it very often tells me the wrong side of the road for my destination. The result is I am often in the wrong lane! I have come to realize I always need to look both left and right as I approach.

I have been told the database does not have side-of-road for each specific address. As we know, odd addresses are typically all on one side of the street and evens on the other along a stretch of road.

There is supposedly and underlying grid in the database and ONE odd versus even setting for the grid applies to all addresses along that road within that grid. That makes sense to me but probably also leaves room for error.

Now, Garmin may just have made that up when I asked them about side-of-road errors. smile

coordniates are off on 765t vs 360

here are coordinates for a paticular intersection

n 47.29.176 765t
w 122.11.717

n 47.48.624 360
w 122.19.527

Navteq says...

I had a conversation with Navteq about a similar issue, the map shows my house at the wrong end of the block. It turns out that they assign 100 addresses to each block regardless. If there are only 5 houses on each side of the block and they are numbered 1400 to 1409 and you live at 1409, the last house on the high end, it will show you at the low end of the block since they assign 1400-1499 for that block and 1409 is "obviously" much closer to 1400 than to 1499. They say it will "sometimes skew the actual location."

As for being on the left or right, I'll defer to the previous posts about that.

Wrong Side of Street

I have the same issue. My 765T says my home is on the right, when it is actually on the left. I believe that my wife's 360 is correct (although it is using an older map set). Mine is always correct, however, when I set it as noted above in my driveway.

I live at the end of a cul-de-sac and the house numbers are somewhat random for the 4 houses on the end. It makes no sense, but they do not seem to follow any logical pattern. If you live on such a street, maybe that is the reason it is wrong.

But that still doesn't explain why the 360 gets it.

coordinate difference

These coordinates are from the same location taken at the same time? When I plot them in Google maps it shows them about 30 miles apart. I must be doing something wrong in the conversion.

Wrong side of street

I've run into this as well, several times.

My old house address was actually shown one the wrong block....

Now that someone said they assign 100 address per block, I can understand how a mistake like that could happen.

Not that I accept the way NavTeq is doing it, but I know why now.

I have found that if we are drive way out in the in the country, the location and addresses are off kilter too about 50% of the time.

I have discovered the same

I have discovered the same thing as others.This is such an odd thing. Boggles my mind why one unit can vary from another with the same map. It's one thing for the map to be incorrect but quite another for it to be incorrect on one unit and correct on another., with the same map. I would love to know the correct answer for this.

Yes, by extrapolating from the entire block, the amount of memory required is vastly reduced; if every single address had to be known specifically, you'd require an enormous amount of memory, when getting you within a quarter of a block or so is usually quite good enough.

Address accuracy

That is strange. Sounds to me like "Home" and "House" are not geographically at the same point.

No one

No one seems to question the accuracy of the GPS receiver in your Garmin. After all, the civilian version of the GPS can have a deviation of more than 10m or over 35 feet. I had occasion when I was driving out of town and my Nuvi 200 shown I was driving on the Trinity river. (it was way off).

Address accuracy

The coordinates I typed in are from an intersection I was at with both the 765t and 360 up and running. I have not had any other issues with homes/addresses on the wrong side of the street.
As I stated earlier, I went to the navteq site and it showed my home on the wrong side of the street but given both units have the latest map updates the only difference is the 765t has 3D map as well.
Since Navteq showed wrong side of street it is probably not a garmin issue but I have a IQue5, 340 and 550 as well and this problem has never shown up before.
Hmmmmmmmm

So you have

2 different coordinates on you two gps's. So this isn't likely a map issue. It's your home setting. Easy way to fix this go to

Plug in your home address and make both of them point to the same long/lat coordinates.

Wrong side of street

I dont' mind it so much being a block off, it's the wrong side of the street that gets me.

I get in the left hand lane to turn into the address and learn all of the sudden it's on the right.

I have started paying more attention to the odd or even street addresses when I get close to my destination.

Try a "hard reset"

My nuvi 750 was giving incorrect locations and strange instructions when I first got it. It was 0.4 of a mile off when I went to my dentist's office. I decided to try a "hard reset" carefully following instructions while doing the setup. Initially I had done the setup in the driveway which has several large trees around it. The instructions call for open skies when doing the setup. I went to a large parking lot with no tall building or trees to block signals.

The result is the unit works perfectly. I even drove the 20 miles back to the dentist's office to check it out. Where is was almost half a mile off before, it was exactly right on the second try.

One of the self appointed experts here assured me that the GPS was right and the maps were wrong. I don't claim the be an authority on GPSs, but the "hard reset" worked for me.

Try a "hard reset"

I did a hard reset and my home is now on the correct side of the street. Still off by 2 homes though. Maybe another hard rest

Where Am I?

When I use the where am I feature, I don't usually get my exact address. Some times, I do, other times...
So off by two houses is ok.

another negative issue with the 765t and also a positive

While down in Anahiem several days ago I did like the lane assist and junction view but I also noticed with POI's while it does show distance if you are at a stop light (stopped)it does not show direction. Since the closest one could be behind you this is really rather crazy. Once I started moving the green direction arrow showed up. Of course I was through the intersection and should have taken a right.
You would think Garmin would improve upon features but more and more it seems they give you a little something but always take away something in return.

350 and 760 are this way, too

My 350 and 760 have always done this, too. So it's not new or unique to the 765.

I know the GPS can't tell which way it is facing until it starts moving. But you would think they could ASSUME that since you WERE moving, you are still facing the same direction when you stop.
