Has anyone experienced a problem like this?

 

I've had my Nuvi 660 for about 2 weeks now. I've really enjoyed using it (my first GPS) and up until now it has seemed to work perfectly.

While traveling home from a family funtion last night on Northbound US 1 and I-95 in Northern Virginia it seemed as if my Nuvi was "confused" as to its location on several instances during the trip. In the 3d view it displayed my vehicle traveling parallel to the road about an inch to the right of the road (where no road existed). At various times, it also attempted to recalculate my trip, presumably because it did not realize that I was actually on the road.

While this was happening, I tapped the signal bar and found that the accuracy was showing that I was picking up an adequate number of satellites and I belive that the actual number was within 19 feet.

I power cycled the unit and that did not seem to remedy the problem, so I then hit the reset button and I believe that that may have solved the problem.

I believe that I have the latest version maps.

When the problem first happened, I thought that it might be a case where because the road that I was on had been recently widened (and not reflected on the map); that that might be the cause for my car appearing to be traveling parallel and to the right of the actual road depicted on the display, but after it continued while I was traveling other major roads, I became concerned...

Has anyone seen this type of behavior before?

Any suggestions?

Thanks very much...

Something similar...

I experience a similar problem in Cape Town, South Africa recently with my Nuvi 670.
I had bought the Southern Africa mapset and installed it. For the most part it worked perfectly.
However on one stretch of the main highway (N2) it also showed me as travelling parallel to the highway and not on it.
It was also trying to route me on an extremely weird route to my destination which I knew to be wrong.
All I can attribute this to is it seems that within the mapset certain sections/ areas are 'stitched' together and when uploaded the alignment is not right. So while the GPS position is correct the underlying map is off by a number of meters.
I took some screenshots of this phenomena and hope to post these on my website within the next week when I have some time.

Also I discussed this with a friend and apparently it happened to them as well. Garmin South Africa told him to delete the maps from the GPS unit and re-install them. Great solution if you have your PC with you but useless if you are 10,000km away from yours, like I was.

Hmmm...

I wonder if you haven't stumbled on some government plot to secretly move primary roads? Maybe, they're doing it really slowly, so no one will notice. The next time you travel these routes, check for construction workers doing that "whistle while looking up in the air" move. smile

Did you have "Avoid Highways" selected?

GPS Lost

I also had a similar problem where the GPS (C530)was showing my car "in the middle of nowhere" after I stopped at a gas station and was trying to get back on my original road. It kept trying to recalculate to no avail.

I powered my C530 off and back on again and eveything was back to normal. Probably just a glitch since it never happened again.

has anyone considered the

has anyone considered the movement of highways? construction happens all the time fellas. highways move, people created the updating mapping and we all know people are not perfect in any way. right?

Sounds very familiar>>>

Off Road Driving

I have had a similar experience on a 2 lane state road in Georgia. I travelled for several miles in a field parallel to the road. Finally the 660 put me back on the road. The road had not been moved given the mature trees on either side.

Not exactly the same behavior but...

I've sometimes seen temporary directional confusion / wrong street displayed when traveling in between tall buildings, such as in downtown Chicago, San Francisco and New York. I believed this is caused by the satellite signal bouncing off the buildings, but it wouldn't explain it going on for long stretches of highway.

Avoid Highways...

No. I thought about that when the problem began, but I looked and it was not checked.

I have not had the problem since last night. Of course I also have not been back on that stretch of road.

Thanks everyone for your replies...

I had the same problem with my 650

Driving north out of Dallas on SH-75 one day my 650 did the same thing (I posted the same question out here). In my case for about 3-4 miles down the highway it kept trying to reroute me to 75 while showing me off to the side. I turned it off and back on and it displayed me in the correct location on the highway again. That was about a month ago and hasn't happened since. I drive the same stretch of highway back and forth to work everyday.

At the time we thought possibly from heat.

Map Misalignment

Have finally been able to post some screen shots of this occurrence on my temp website.

Hope this is a help...

Similar Problem

I had something similar happen to me while driving around Austin, TX earlier this year. I was driving on an interstate, but there was another road following the interstate. My GPS couldn't decide what road I was on and showed me skipping around and it was trying to recalculate.

I also noticed that if I am zoomed in too far the arrow doesn't follow exactly the road either and shows it being off to the right, or left.
