Fix for Screen Issues for a Nissan Presage 

Hi There
This is a fix for issues with Aircon/Heater/ Stereo and other things.
This also apples to many Nissan like tiida, murano and many more as they use the same controller. If you have flashing on your screen or your screen is dead in the car. Watch this as it should help. Please depending on the car this unit will in many locations. The Unit that is causing the issue is called a DCU-620?G. See video for more information.
