hershy314 Posted January 16, 2017 Report Posted January 16, 2017 The past couple of months I've been having to take trips to Springfield MO to see a dentist. Finally got my dental work done, but that's not the purpose of this post. The purpose is this. We have a 2007 GMC Acadia with the bose sound sytem and factory navigation. Is it possible to change the background of the head unit to something less boring? If so, how can I do it. I'm not interested in getting a different head unit. This one works just fine. Thanks for any help. http://athphotography.deviantart.com/ http://www.youtube.com/user/hershy314
