NESA head unit





The prev. owner of my car installed some kind of made-in-China NESA head unit. It's lighweight, cheesy, flashy, and will be replaced, but in the mean time, he left a DVD in the player and I cannot figure out how to get the dratted thing to eject.
NESA NSD-360
Looks like originally it came with a remote (I do *not* get remotes for car audio - every function ought to be on the control panel with no need for a remote!)
Anyway, I went to the company's "Front" website and asked pretty please for a user manual and got no response.
So... does anyone here know how to make this unit spit out discs? I've tried the really obvious stuff, like pressing and holding the "open" button...
