1200 miles is not enough for an accurate rating, but a couple of items really irk me. First being the destination cannot be changed while driving unless you pull over or call the enform service that will COST you $250 bucks after the first year. Second is the audio. Lexus says for safety reasons you are blocked out of scrolling for artist on the IPOD, USB and CDs. However can you can scroll tracks, select from over 200 satellite channels and have full use of a Blue tooth capable portable player. What's that all about? It should be all or nothing. And if it is nothing they will be at a competitive disadvantage. Lexus needs to have a consumer focus group on this one.
