I have seen many people ask how to get news, weather, video, iPod music, google maps, and how about ANYTHING that runs on your iPhone to display on your in-dash screen.
NAV-TV with AV input Harness
Apple AV Output Cable
ScreenSplitr (Jailbreak your iPhone, search Cydia)
With your iPhone plugged into your myGIG using AV cables (I’ll do a full write-up later), run ScreenSplitr. Thats all…
You will see your iPhone Screen Mirrored on your MyGIG. Any application you run on the iPhone will display on the myGIG screen. Imagine the possibilities… Pandora, Google Maps, Red Light Cameras (Atoll.CoPilot is cool), SlingPlayer (Watch live TV on your MyGIG Screen). The only Issue I have with screensplitr is frame-rate. It does compress the video output and freame-rate is not the greatest due to the mirroring on the iPhone 3G, but it works and looks good enough for now!
