Has anyone gotten this to work? I have a 3GS iphone and a Z120BT and am unable to get video output on the Z120BT as seen in the demo videos circulating the internet. I have put the receiver in iPod mode and can play other video sources on the head unit, but not the Motionx app. Is this due to having a 3GS vs. a 4g iphone? I know netflix won't do video out on a 3gs. Thanks
