I can see how cheaper it is compared with my 4-year old RNS-510 Nav OEM system in my VW CC that uses Navteq maps. Navteq include even tollbooths and controlled access communities in their data, something tha it is completely missing from my 2012 M3 iDrive.
BMW still uses Navteq in Europe, I believe, at least that was the case last time I looked.

Interestingly enough, when I looked on Lexus' Web site I found this: "Lexus sources its map information from more than one supplier", which I take to mean that data from multiple suppliers (presumably Navteq and Tele Atlas) is combined by Lexus.
Freude am Fahren.
