I don't know if it's database related, but it will give you voice commands to make a turn where there is no turn to make.
Definitely not nearly as refined as my wife's Acura TL system.
Even my 2000 Bmw 323i has a neater system.
It just seems cruder than the best, it does generally work.
My 2006 Nav does show a newly built (less than 8 months) road in my area.
The system could use refinement, generally.

I don't have issues with phantom turns that a lot of people mention (although on Route 1 in Delaware for about 10 miles I was driving in the cornfields while the road zigzagged back and forth per the Nav 
), but the icon database is pretty skimpy and downright inaccurate. I don't think it's even a case of being out of date; there's just a lot of stuff missing or in the wrong place. For instance, in my town where there's a row of storefronts along the main avenue (and has been for 20 years at least), the Nav shows a Texaco station 
.

Report Nav database problems to: support.na@teleatlas.com. They are very responsive. I have seen changes I suggested reflected in v2 of the DVD.

Nav/denso/gdt Errors
When I picked up the car I asked the dealer to show me how to program my home address. The system would not accept it ( I didnt know how to get home 
). Even though the road in front of my house was there for 30 years the Nav system couldnt find it. Later on I discovered why- the road was miss labeled. This led me to investigate further because this road is a dead end and the Nav shows it connecting to another miss labeled road.
What I found was that the data base supplier GDT was bought out by TeleAtlas last year. GDT and TeleAtlas were struggeling for money and the majority of TeleAtlas business is in Europe. Bosch bought a major share of the business . GDT had the original data base created in INDIA ( perhaps from Rand McNally and aireal photos ) . Whatever the case , it seems that the accuracy of the data base is not an important point at this time. The main objective is to get the hardware and disc sold, regardless.
I contacted the dealers service department and they in turn contacted Chevrolet who advised us of the TeleAtlas web sight were we could give them the error information.
Unfortunatly that error information goes into some sort of " black hole " in New Hampshire and may never appear again. GDT claims they do not issue corrected discs and Denso wasnt sure what I was talking about or who their customers were.
The 2006 Covettes with NAV are entitled to 2 up dated disc. That doesnt mean they will be accurate or have the requested corrections. I am not sure how this fits with the warranty for defects in workmanship and material because the disc is still flat and round so it must be ok.

That is really only important in that I can't depend upon the system to get me through a housing development, even if it is on the map. It may turn me loose a mile or two from my destination saying something like "data not accurate enough to get you there, you are own your own."
I always have to have a backup plan.
My Garmin Quest with Mapsource is much more reliable.
