If you properly connect power on the six main wires on the M13 connector, it will boot up and work. I have confirmed this on a 86110-47081, I believe it will also work on the newer MFDs (86110-47230). On the 86110-47081, on the M13 connector, put 12v+ on pins 1, 10,11, & 12 and GND on pins 2 & 3 (NOTE: 86110-47081 can be found on base models (no camera, no Bluetooth) 2004-2009.) on a 86110-47230 (or any 2006-2009 hi-res screen), on the M13 connector, put 12v+ on pins 2, 3, 10, & 12 GND on pins 1 & 11 Putting a 5A fuse on the 12v+ power is a good safety measure, insulating the wires and pins is a must! The LCD creates high voltage, do not power up the MFD if its metal case is open! Doing this will probably sterilize kittens, cause your dog to run away, and turn your hair white. If you are not an experienced electronics technician, do not try this at home.

The 2004-05 navigation MFDs (86110-47070 (early 2004) and 86110-47071) also use the "lo-res" M13 pinout. "Hi-res" MFDs would include the following part numbers: 86110-47230, 86110-47220 (w/nav) and use the "hi-res" M13 pinout. I don't know about 86110-47210, if you know please post here, thanks!
