Problem with Navteq map or Garmin unit?

 

Has anyone tried driving from near the Washington DC area to Baltimore, MD using US-29 going through Columbia?

This is the second time I'm trying it and the issue is still there even after map update from when I first noticed it in december.

I was driving from my friends place in Hyattsville, MD to Baltimore, MD. The GPS told me turn on New Hampshire Ave. I turn and keep going straight. Then it says "Turn right onto US-29 South", but US-29 North was the one highlighted on the map screen route. I follow US-29 North because I know exactly where it is I'm going. US-29 South goes to Washington DC, US-29 North goes to Columbia/Baltimore.

But wait, it wasn't finished yet.
When I got onto US-29 North and kept on driving, it told me "Continue on US-29 South"
I became confused and later turned off the GPS unit.

The highlighted route on the map screen was correct, the directions given(both the text and speech) were absolutely wrong.
When I took US-29 North, it also did not tell me "re-calculating".

Who is at fault, Navteq or Garmin?
Has this problem already been reported? Is this a well known problem? Has anyone experienced this problem when driving the same route?

Sounds Like . . . .

. . . A problem you need to talk to Garmin support about. As a side question, do you happen to have any kind of blue tooth or FM transmitter anywhere in the vicinity of your power cord? I did once and the 780 had me going well off the map. It’s the only thing I can think of. If no to the question, then the suggestion of Garmin support would be the way to go.

I would take the instruction to mean that the road is "US 29 South", and it wants you to turn right (north) onto US 29 South.

South or North

Turn right on East Main Street means turn left onto West Main Street?

I would think that South US-29 would be the same as South Main St. But US-29 South would be the direction you would travel on US-29.

Garmin should be made aware of the problem.

TTS Text

I have also occasionally found that the spoken text did not match up with the route. Normally the "route" is correct, but labeling is wrong. I do not know if it is a Garmin or map problem with the labeling.

What is the specific map number, and which unit are you using? What are some addresses (generic) that we could use to see if it is an old or new problem?

To answer your question

To answer your question, the problem is with the map information, not with the GPS. Some how the labeling got messed up for the northbound lanes. When I'm in an unfamiliar area, I usually check the route turn by turn just to avoid any surprises.

Another anomaly that I've seen a couple of times is the unit telling me "In .4 miles, turn left on West Belleview Ave." when I'm already driving on West Belleview. At the point where it wants me to turn, the road narrows from 4 lane to 2 lane, and for some reason, the way that the map is coded makes the GPS see that as a turn. I've run across this in a couple of places here in the Denver Metro area.

I guess we are a few years away from a GPS autopilot... still gotta use your noggin.

The naming convention that AASHTO uses for US Routes (when they divide into into two routes is to put the "South" at the end. See this article referencing an accident on US 29 South: http://www.independentmail.com/news/2008/dec/30/three-car-ac... .

All that being said, I find no evidence that US 29 is, or ever was, one of the official divided highways. Further, I cannot make my 660 turn right onto US 29 (Georgia Ave) from New Hampshire. If I turn onto it from another street, it calls it Georgia Ave. I'm using the 2008 map. Maybe Daniel, or someone else with a 760 and presumably newer map could run a quick simulation to see if he gets the same instruction as Lothario. Weird.

Unfortunately I'm unable to re-test this anytime soon because I only drive to the DC area every 2-3 months.

I wonder what would happen if I actually went on US-29 south like it told me to(which will take me to DC and not Columbia/Baltimore!)?
Will it say "re-calculating"?

I will also try using that route when going to DC next time to see if it calls it US-29 "North".
My GPS usually takes me through I-95 when going to Hyattsville, but US-29 when going back to Baltimore.

South means going towards DC and beyond.
North means going towards Baltimore, Columbia, New York, and beyond.
I don't see how they can mix this up.

Direction?

Thank you for that bit of information BentBiker. However, in my neck of the woods, signs at intersections refer to the direction first then the name of the street. So you could turn north on South Main Street. However "Main Street South" would be a different street than "South Main Street". Also, what would make you think that I thought US-29 was a divided highway?

What I was trying to say was that the GPS map might be wrong in it's labeling of US-29 South but the routing right.

Interesting.
I suppose then that means the DC/PG county/Maryland state government need to change their green signboards for US-29?

Whenever I have a problem

Whenever I have a problem like this I go to an electronic store such as Best Buy or Fry's where they have display of other Garmin models. I set the GPS to simulator mode, and simulate the route where I'm driving to see if it do the same on other models.

I will try and simulate on my c580, running 2008 maps and see if it is an old problem or not. My 760 at home has 2009, so we can see if it a .11 problem or not.

Map

I have noticed something very similar near Nashville which was fixed with the last map update I did to the unit, sounds like the fault is with the map info.

I'm obviously doing a poor job of explaining myself.

Federal Highways (US Routes) are named by the American Association of State Highway and Transportation Officials (AASHTO), according to totally different set of rules than local city-named streets. Regardless of the location in the US, if a US Route divides along any stretch of its length into two separate roads, those roads will be named US XXS (south) and US XXN (north), or E and W. Perhaps you remember US 20 and/or US 50; both previously had sections in Ohio that were divided for a portion of their length -- US 20N,US 20S, US 50N, and US 50S. That is just the way AASHTO does it. Thus, it sounded to me originally as if the section of US 29 in question might be such a divided section; when I Googled "US 29 South" and found articles referencing locations on "US 29 South", it looked even more likely. However, when I later looked up a list of current and former divided US Routes, US 29 is not listed. I never thought you felt US 29 was divided.

What's with the attitude? You are the one who asked for help. And as I said, "I find no evidence that US 29 is, or ever was, one of the official divided highways." The signs are probably fine.

BTW, you don't have to drive the route to test things -- you have the ability to simulate a route on your unit.

No attitude was displayed from the post you quoted.
If the signs are perfectly fine, then something else has to be the issue.

I didn't know about the simulation part, but I suppose I can do a test drive tomorrow morning.

Simulated

I simulated your route on my 760, (2009 maps sw 2.6). The display shows "Right on US-29 S to Columbia." Is the S supposed to be "spur" that gets translated south with the TTS? I am not familiar with the area, but had similar results with mine. I will try and check my c580 when I get a chance with older maps.

It's not a Spur as far as I know.

US-29 north goes to Columbia, not south.
US-29 south goes to DC.

Both US-29 north/south are on the right hand side, but the turn for north comes before south.

Not a 2009 mapping issue

My c580, (2008 map sw 6.4) shows "New Hampshire Ave to US-29 S" and says take ramp to US-29 South. So this is not a new problem and probably a mapping issue.
