My DVD version is .02.1 Mine only gives me route guidance on major highways, in other words it only highlights your route on the major highways, if your destination is on a country road, you have to use the guided arrow, and the voice navigation lady states that route guidance cannot be provided in these areas. It sounds as though they may have upgraded the route guidance with the version you have, I think its more important to have route guidance on back roads than it is on major highways. I contacted Toyota about this last fall and they told me there was an update for the NAV system, they just couldn't tell me what was new with the update. I like to know what I'm getting when I spend $200 + for a update.
Thanks,
Robert
