The navigation system does not have voice commands for "suspend guidance", "resume guidance", "cancel guidance", etc... this means in order to stop navigation it must be manually turned off while the vehicle is in motion. This requires manually entering the command which requires watching the display and causes distracted driving. It is not a safe condition and I am unsure why Toyota/Lexus removed the voice commands since both our 2006 and 2007 Toyota prii have them and are much safer cars to drive because of it. Also Toyota/Lexus has modified the navigation so that it continues talking even when using the bluetooth hands free phone option. Which means the navigation voice talks over your phone call. This again can cause distracted driving as you are talking to someone and suddenly the loud navigation voice begins speaking as well. This is another unsafe change Toyota/Lexus has made as both of our prii do not allow the navigation system to override the bluetooth hand free phone. I am not sure why a 2013 Lexus that is 6 years newer than our prii and costs twice as much has such an unsafe navigation system but it needs to be corrected as soon as possible. Both problems readily cause distracted driving.
