You can take the whole upper section out in order to enable you to wrap around the edges.
There are 2 screws on the underneath of the grille that you need to unscrew, then 2 screws on the top at each side, and 2 clips as well, once all of those are off then the grille will come off.
If you do wrap it, then it is worth filling in the numberplate holes first as otherwise they show up through the wrap.
