Remove the four nuts along the window where the dash is mounted using a 10 mm socket. This pic shows the far right one.
Second one from the right was removed. The same set of two nuts is in the left side.
Put the shift lever to 4th gear before starting this step if yours has manual stick. Lift up and gently pull the dash unit. It is much easier with two people.
