I'm a 2010 GT-R still with original MFD/control unit. Today the MFD decided to stop functioning and just displayed a solid black screen. No GT-R boot logo or any dials. Also none of the buttons seem to do anything either. Stereo/HVAC don't actually do anything nor do the respective steering wheel controls.
I checked a few usual suspects like fuses in the footwell but didn't see anything blown. Also did the battery disconnect for about half an hour and tried to "power cycle" the system.
Any other ideas? (besides just upgrading to legertas' updated units)
