now is the mirroring iphone thing dlna a software thing or is it actual new hardware like a totally different screen for the movies if so any pictures would be greatly appreciated
I have not had time to try this yet. From what I understand its software, not hardware, that uses an app on your phone/tablet to project onto the existing screens. In GM's words "WiFi allows devices to wirelessly project onto their vehicle screens on the in-vehicle screens through Digital Living Network Alliance (DLNA) (can only wirelessly project from one device at a time)"
