Hello, I just purchased an 08 Prius. Its loaded and does have Nav. It came with the basic Coastal Tech Lockpick that unlocks the nav while moving option but I want the one that adds the audio/video input. My question is this; I want a device that can hold movies, tv shows and maybe even music so I can play them through the input that the Coastal Tech device adds. Id even be open to other input options. Coastal Tech was the first one I found. Unfortunately my HTC Surround does not have a video out option otherwise I would be all set. So what do you guys think? Buy an iPhone 4? Buy an auto pc? What else?
