I have 06 LX and lexus personalized settings allows you to roll all windows down by holding unlock, unlock ALL doors with one click etc. Does techstream allow your to make these changes or do you have to go to Lexus stealership? I am primarily interested in making my remote unlock all doors on one click drives me nuts to have to press 2x. Also would like to change some lighting options too. I don't have techstream yet (I've been using icarsoft)
