Twice now I have manually entered an address into the nav system and when I reviewed the routing, everything looked correct; it was in the general area I expected it to be.

It navigated us close to the destination but near the end, both times, turned us into a residential area and took us to an address different that what I had entered. When I checked again, the address number and the street name were different than what I entered but both were close to the final destination.

I have no idea why the address and street changed. Have any of you experienced this? Any idea what might have happened?

 

Could be a coding error with the map. I haven't had this in the Lexus, but this happened to me using the Hertz Neverlost navigation once.

It is possible to code addresses as old and new, and if a current address is coded as an old address for a different current address, then it will automatically change it to the other destination.

In the Hertz case they were 10 miles apart and I was late for my meeting.

 

As it turns out in most cases where you are attempting to locate an address in a development, Navteq doesn't have the street numbering down to an exact science. Data available from developers do not at all times include number of lots on a street, etc. As a result the map developers algorithms are off by a lot or two.

 

Both cases resulted in the nav bringing me to a well-established (read old) neighborhood. I wonder if I need to take this in to the dealer for a review?

 

Ed, I may have read your post wrong. It seems your nav is not even close in a geographical sense. Sounds like an issue.

From my experience I can never get an address destination to get me exactly to the correct number. Street names have been right on except in one instance, but that was a Garmin.....unrelated to a Lexus.

 

My Tom Tom GPS this past week in the Detroit area took me close. Seemed the address I was looking for was divided by an intersecting street and land. In other words, same street name for two different street. One was residential and the other was commercial.
