Not yet, Bob. But I will post a brief review in a new thread hopefully over the next few days. It would have been done already, but I wanted to take at least a couple of pictures and our one and only digital camera stopped working . My wife ordered a new camera, but it will will likely take another few days to arrive.
But I've been using the new GPS receiver (Qstarz BT-Q818X) daily, and I'm happy with it. I still want to do a side-by-side comparison testing with BU-353, and I will have to go downtown, among the tall buildings, to do that.
