Every piece of software, desktop or otherwise, requires some investment of the users' time and effort to learn and master. Although it's only been about two weeks since I took delivery of my 2004 ES330, my wife and I find the Nav system intuitive and user-friendly. It's user-interface has been improved since the previous generation, and the routing calculation speed is significantly faster. However, I was dissapointed to find that the 5 million POI database lacked the complete listing of certain catagories of businesses. For example, the system failed to list the nearest UPS office or FedEx office. Apparently the complete yellow page listing database contains 12 million POIs.
