for in your rear view mirror? Thats crazy, but yeah I'm not sure how big your rear view is but if its the size of the ones I'm used to, such as my '95 monte carlo (which shouldn't be too far off of your's then I wouldn't go any more then a 2 line. Something like this http://www.matrixorbital.com/product...character-vfds should do it, but check the thickness to see if its okay.

If you want to/have to go with usb then I'd go with this one http://www.matrixorbital.com/product...character-vfds its just a little bit bigger. What are you going to be displaying in it? And are you sure that you are comfortable with the software available for it, different screens use different software it seems. I'm really not sure how good the other screens or software is becasue I've always been ultra happy with my matrix orbital and lcdc solution

I was just thinking, and I could even put this screen as a flip up screen on the dashboard and use it for gps only... my god talking about my vfd I could even prob. make something up so that it would flip up only when I had my gps software running or at the very least have it go up via the computer.
