The screen is in the middle and as you know on the VX you can see the most on the edges of the rear view mirror becaouse of curved back window. So, it may be possible to kind of fill in the gap if set up properly. Also having an on-board OBD2 (with an bluetooth ELM327) car PC and DVR is a double plus. Just don't play Angry/Flappy Bird(s) while driving.
