This doesn’t affect anyone except those living in this area, and someone who is traveling through.
Highway 121 South from McKinney, TX to Preston Road is mapped in correct. This road is a divided highway with 3 lanes going in each direction, North and South and has been under construction for the past 6-7 years (going to be a Toll Road). It goes to the Dallas North-South Toll Way. However, the area I am pointing out has been finished at least 2 years.
Once crossing Stacy Road going South, the GPS will instruct you to turn left on Alma Drive, and then turn back right onto Hwy. 121. If you do this, you will be headed directly into 3 lanes of 55+ MPH traffic. It is the same going North, after crossing Coit Road, you will be instructed to turn left on Alma Road, then right onto Hwy. 121, it will head you into 3 lanes of fast traffic. There are other instances of this on the stretch between Stacy Road and Preston Road. If you live in the area you can work around it, but out of Towner’s following their GPS, especially at night will have a problem. NavTeq has been told about this, but no replies from them.
Usually the map is at least 2 year old so for 2006 GPS map, it is about 2004. I used TomTom and the latest 2007 map is fine in 121 area.
Jeff, does your TomTom have NavTeq maps, and does your TomTom take you through this area I pointed out with no problems? My 660, and two other Garmins 550C's stay screwed up all through this stretch of road.
TomTom uses TeleAtlas in US and both Navteq and TeleAtlas in Europe. I used 2007Q1 map in my PDA phone and the 121 is pretty much up to date. Hardin/121 intersection, Custer/121, etc are fully detailed one way service roads with proper U turn mapping and overhead ramp update. It even shows the 121 Custer intersection freeway overpass (avoid the traffic light). TomTom usually updates map a bit more frequent. I did hear that NavTeq is more detailed as people compared NavTeq/TeleAtlas in Euopean market for the various TomTom update. Personally I am pretty happy with TomTom to date.
Edit: Some complains about the TeleAtlas map issue for TomTom is that TomTom map for the PDA release tends to be less detailed due to its desire to fit the map in 1 GB SD card. The map for PNA (personal navigation assistent) has more detail. For example, TomTom North America map is 1.4 GB and TomTom USA_Canada is only 900 MB. Besides more POI, map detail probably plays a role.
Jeff, when I am going south from Stacy, my Navteq does not show me both north and south roads. Only the north. When I am going south, it indicates that I am out in a field, not near a highway. The 121 Custer freeway overpass is sort of tricky...just have to remember to keep in the left lane going north. No signage to tell you to keep left until you are right upon it (that I recall). Maybe Navteq will get with it someday.

I live in McKinney, just off Custer.
I just ignore the GPS when I am on 121. It has me in fields until I get near Preston and it tries to make me take some of the strangest bypasses to get back to 121. I'm thinking I will skip the next map upgrade and wait until more of the work on 121 is done.
What happen is that the NavTeq map still used the old 121 in this section which was no longer existed (now pretty much buried within the land divider between the new one way service roads north/south bound). I do not know if NavTeq did not update the map or Garmin was too cheap to pay for the update. For TomTom, the road was updated from TeleAtlas since Dec. 2006.
I know, or think using a GPS is a big percentage of common sense, the rest is relying on the GPS. I don't remember seeing any disclaimers concerning liability, other than Garmins splash screen that tells you to keep your fingers off the GPS while driving. Where, or who would the liability fall on (other than you), if you did go up a one way street, or road at night that the GPS sent you, and had an accident?..... I suppose this is where the common sense kicks in.
seems to be an oxymoron at times....
Keith, would you mind explaining you comment please?
I've observed that sense is something less than common in much of society at large...of course, I'm not lumping anyone here into that group.
I shortened the long url so I hope this works. The last paragraph in the red box should answer any liability questions regarding accidents occuring while following your gps's every command.
Have a happy and safe 4th:)
I drive through there on a regular basis, and I noticed the same thing. I'm hoping it will be corrected on the next update.
