Its dead easy. To screws either side of the bumper in the arches and then a load of plastic pop rivets along the top of the grill (prize them out with a flat head screwdriver) 3 or 4 more plastic rivet things under the bumper and that's it. Just pull it off.
Cancel that. just noticed yours is a 6th gen. sorry.
This guide would have been really handy if you owned a 7th gen.
Mate it's the same on the 6th gen as well. Had mine removed yesterday. I removed all the plastic clips at the bottom like a nutter. Don't think you have to remove all of them.
