I have a 07 STS with the 2009 Nav. disks. Today the wife and I were out house hunting and punched in the address of a new home in a subdivision that I'd say is at least 2 years old, maybe a little more. Anyway it couldn't find the address but we knew the subdivision and was able to find the street and house. All the nav showed was a big white blank with NO roads of any kind. Since this was the last house we wanted to see I hit the home button and it proceded to take us out of the subdivision street by street but without names. If it knows there are streets there why don't it show them and if it can show them it should be able to name the streets as most subdivisions are plotted out and the streets named when applying to the local government. I thought this was weird. When I got home I checked my Garmin with an 08 map installed and it not only showed the subdivision but also all the streets and accepted the address and showed exactly where the house was.
