Good Car But Don't But Poor Dashboard Technology
 The navigation system leaves a lot to be desired.  I read some of the other reviews and I agree that it's not intuitive to operate and the lack of functions that can be used when moving is not good.  I have an example as to why I don't trust the navigation system.  I was 2.5 miles from home.  I know how to get there.  To show the issue let me say I compared the Toyota system to my Garmin unit, Apple Maps, and Google Maps.  All three non-Toyota devices computed the route successfully as 2.5 miles and about 6 minutes.  The Toyota wanted me to take another route which was 3.9 miles and 11 minutes.  Not good.  I pulled over to better use the controls.  The Toyota showed 2 routes (the alternate was the same as Short so I am not including that).Quick  3.9 miles  11 minutesThe voice recognition  system is also poor.  I set up the "training" session with the unit.  If I say "Call Jane Doe" and Jane Doe is not in my contacts it does not tell me that it fails.  So I have a difficult time doing voice commands.  I then contact Toyota and ask if there is a way I can disable the dashboard "intelligence" and talk directly to Siri.  They say, "no:.   They add that it would be dangerous but all I have to do is push a button on my phone and it DOES understand me.Short  2.5  miles   6 minutesHow can the quickest route be 5 minutes longer than the "short".  The "short" was both less miles and less time.   The Garmin understands short to mean distance and quickest to be the fastest time.Lastly, if you have a way point (destination) you can't cancel the route, the Toyota option is to "Delete" it.  But you are not deleting it as it still goes into "previous destinations".  Just bad terminology for a navigation system.  I have engaged Toyota on this and this and other issues that I have and there is "nothing they can do"If I go some place that is new, I take my Garmin.
