Phatbox... Does anyone know anything about these?

I have one in my Jetta (TDI) and have a dream of being able to swap it into my Truck after I install a new Stereo, but so far I haven't had any luck. I have talked with a couple of stero shops and looked around the web, but have come up empty so far. Anyone have any thoughts or insight about this?

 

Well, after extensive research, I found out that being able to swap back and forth isn't an option unless I installed a VW headunit in the truck. So, I'll just go with a decent stereo/MP3 player with good speakers in the door.
