shadow, if you have a double-DIN opening in your car then why do you
need a motorized/swivel monitor? with a little modification, you can fit a 7" LCD into a double-DIN opening. are you sure your car's opening is only "2 DINS"? many cars factory openings (like mine) are considered double-DIN but are actually bigger (the radio might be d-din, but the opening may be bigger). for example, I can fit an entire EBY701, enclosure and all in my "double-DIN" opening
when I first entered into this hobby I went through the same thing... I tried to find pre-built monitors that I can just plug in and use. but I soon came to realize that no good solution exists. if you want your system to look good then you'll have to spend a fortune on a double-DIN unit like the G4, or you'll have to break down and do some modding/fabbing to fit a panel in yourself.
good luck
