Re: 2008 hummer h2 Bluestar Install
Hi your nav radio does not play dvd's on screen and the GMX322 will not change it so you can watch on screen. Its unlocks 2008/09 hummer and 2007/09 gmc trucks nav units that play dvd's on screen, to play when out of park or while driving and to plug in a addresses while driving. Its also lets you turn camera's on any time if if have them. Hope this helps.
