I have a 2007 Prius with the NAV system.  One of the huge pains in the butt is the "I Agree" requirement when you go to the map.  So whenever I show the map after starting the car I must first "Agree" to a disclaimer that says I will not use it while driving.  It is very annoying!

Well the new 2008 Prius does NOT have this requirement.  It will just show a short disclaimer then go to the map. 

Last night we had a friend over for dinner who has a 2008 Blue Prius (very nice color).  We took his MAP DVD out of his car and put it in mine.  Right away the system starts to do an Upgrade.  This kinda scared me because I was not sure if my old DVD would continue to work.  Well part of this upgrade was that now my 2007 does NOT require me to press "I Agree"

While I know that there are "lock picks" out there that will fix this issue.  This is a fix that will not require you to take apart your dash.
