Well, as the author of AGPS. I can understand why NavTech want to kill this product. The AGPS is much better and conviniet than most of the in car systems, especially for those who really plan their trips (pre-planned their point-of-interests, real estate brokers who plan their tours...etc.)
NavTech and Microsoft has been constantly monitor AGPS website since Auguest 2001. It seems to me that this is the conclusion they decided.
Well, too sad. Anyway, just FYI, I've some idea of planning on a software & process that allows public to contribute to a public domain digital map database. Now a day to own a GPS in a PDA/Laptop/Java-enabled phone is really common. To defeat NavTech, that's the only way.... Let me know what do you think...
