Hello, I've come across this video http://www.youtube.com/watch?v=pDgea...ature=youtu.be

I'm trying to figure out how exactly how this is being done. I'm interested in putting the new Galaxy Tab 7.7 in my dash, but really don't want to use an external volume knob.

Also, AFAIK the G-tab lacks any type of line-level audio outputs, what are people using for this?

So I have to say I'm scratching my head on how this is done...lol.

Links are appreciated!
