Seems to be two or even three different GPS puck versions? I don't think the Vision GPS part is compatible with the Vision+ GPS part.. they look really similar but the Vision has that extra cable/connector. So which GPS part is for the Vision+? The Part 1 from the Phantom 2? I've looked around and I didn't find a specific GPS circuit part for the Vision+.. Trying to replace a cracked antenna (the whole round circuit board) with the right one.. I bought a Vision GPS but it definitely didn't work on the Vision+ *Just one to note that the Vision sure locks on to satellite really quick.. wish the Vision+ was as good. the GPS circuit is so similar, what do that cable/connector do on the Vision?
