I was able to find instructions on customizing the startup screen but the same doesn't apply to the screen off. I've named folder ScreenoffImage and it says no files found. Same files as the start up screen. What am I doing wrong? This is for a 2014 ES350. Any help is greatly appreciated This is hubby's car and I'd really like to show him up that I know more about his car than he does! I at least was able to figure out the start up although I doubt he will notice the image lol. Thanks, Lucinda
