Trying to remove the big plastic section next to the battery compartment. I have removed the 8 small torx screws but the panel is still being held in by this little buckle thingy which I have pointed a white arrow to. Any help to remove this piece would be great, thanks. As you can see I can slide out the center piece but this does not seem to release anything

 

I figured it out, slide it to the right !!!

 

Next Question. How to remove this bracket holding down the box ( Nav unit ?) below it ? I need to get access to the grommet behind this box to get a wire into the battery compartment. Thanks
