Front bumper and Parking Sensor removal

[snapdragon]

Thanks neeldub, that's a great article and pictures.
I need to replace my low-tone horn fanfare and this info. will be what I use to get the bumper off. Although I see from your photo I may be able to give it a sharp prod through a hole in the upper grill and maybe it will fix it as it started off just sounding like a strangled duck.
