2015 Genesis Coupe 3.8 Nav Hack to access Engineering interface

Description

How to access Hyundai Navigation unit's engineering interface and Windows CE. Car needs be in ignition on mode with radio turned off. 3 taps on top right, 3 taps top left and 2 taps top right. While playing with Windows CE I tapped shutdown button and ended up with black screen. To get it back turn off the ignition and open driver side door to completely shutoff the system. Wait few seconds and it should be back. Reddit: https://redd.it/5ya4tj
