For me they are just tiny thumbnails, but he sent me the full-size ones. They show the factory head unit being relocated to the trunk by extending the wiring harness, and then installing an iPad holder in the dash. But that doesn't fully help me; I have an older car (no bluetooth, no hands-free, no camera) and need to figure out how the data flows between the various components. On his car it is all done with bluetooth and there is a bit of conflict between devices.
Numerous sites show that an iPad or iPhone can be connected by WiFi to the static IP of the camera and still have some connectivity through other means. Exactly how much, I don't know, but I'll try to find out.
