I'm not convinced the Navteq maps are any better than TeleAtlas. In particular, on my street the addresses are all wrong, and now my house shows about 1/4 mile further down the road. I tried a route between my home and my office, and the route was NOT the way I would normally go...I had to force the software to my route by selecting waypoints. The 22.214.171.124000 software with 2008.1 maps selected my preferred route right off the bat without any manipulation.
Also, I've browsed through the POIs for my area and find that many are missing compared to the 2008.1, as expected given that there are only about half. Unfortunately, some of the ones missing I use, like my local bank branch.
And no, I couldn't get the 2008.1 POI files to work with the new maps.
(and that's not to mention the usual exit/resume problem that plagues all new releases and the fact that there is no dimka skin yet
...but that's fodder for another forum board)
