    Post 20x4 LCD Noise?

    Hey all. I recently bought a L2014 20x4 LCD screen from EIO. (http://www.eio.com/lcd2014.htm) I hooked it up inside and it worked good, but with a little noise, nothing too bad. I took it out to my car and tried it out and the screen is almost unreadable. I'm using an inverter, could that be causing too much noise on the line? Also, my cord it maybe 7-8 feet long. Would slapping a couple ferrit beads on help this? Thanks for any suggestions!
