Removal of Radio 1997 primera sadan

HI, i am trying to replace the factory radio with a better stereo i have. However i cannot get the black casing off. I unscrewed the bottom screws off and tried to lift it off but there air ducts at the top dont let me take it off. How do i get the air ducts off it so i can remove the casing.

thanks

Hi, if you have undone the screws you need to put your fingers into the top air vents and pull. Dont be scared it will come off the clips in the end. just give it a few hard tugs.
