i dont want to watch front dvd but on a long trip my wife wants to sit up front and watch a move, besides, i would like to change sound, input driving (wife or passanger) address into the nav. i heard the if u go to the dainogists (spelling oh well) menu on the nav- u can deactivate the lockout while driving but it resets when the h2 shuts off. this will work for me. there is another way- u install a wiring harness behind the unit for $250 (coastaltech.com) easy to install, but y should i buy it. my ? is - does anyone know how to get to the dianostic screen? it is built into the system sum how. i read sum areas on the touch screen has hidden buttons.
thx
