I have a dual screen setup for the MX-3. I sold my MX3 back in January and didn't sell the screens with the car.
The top screen is built into upper vents/AC switch. It's a MIMO UM-720 USB computer screen. I added a touchscreen plate to it. I rewired the power switch and brightness switches so you can control them through other buttons.


The bottom screen is a Lilliput Eby-701 VGA touchscreen monitor.



These need to be hooked up to either a Car Computer or Laptop! I can help you with that stuff if you need.
I'm posting them here before I put them on eBay. Shoot me an offer and we'll go from there!
Thanks,
Tim
