Anyone try cheaper ebay TV-in-Motion?

I have looked extensively at units to allow the dvd to play while driving. I know that Nav-TV makes one that WILL work on US e70's, but the price of $500+ dollars for such a unit seems a little overpriced. I found a power-seller on ebay that claims they make a unit that will work, and it's half the price! Has anyone tried it on a U.S. e70? It looks almost identical to the Nav-TV unit.

Here's the link to one of them..
