Navigation big disappointment
 I purchased the navigation system and entered a destination only to find out a major interstate that opened in Nov. 07 is not included on the DVD. I have version 8.1 (the latest version). The navigation system sends me the wrong direction because there are no current updates. I have a $250.00 TomTom that is updatable on the internet and a much more useful tool than the $2000.00 navigation system from Toyota. The Sirius/XM is over priced from the dealer, I went online and found a $400.00 kit that I installed in 20 min. and works just like the OEM version.
