Having fitted a reversing camera myself quite recently I can say that removing the handle is a real bu33er!
After removing the two fixing nuts there are plastic tabs at each end of the handle which have to be depressed from the inside of the boot lid while pressing on the handle to ease it out. If you look at your reversing camera you will see these tabs. You can’t actually see them when the handle is in situ, but they are accessible (just) through small holes in the metalwork on each side of the handle. You may not see the holes at first glance, but they are there! You will need a tool shaped rather like an Allen key to press the tabs in through the holes. Very fiddly job. Some people actually use an Allen key, but I made up a custom tool from a 6 inch length of 1/8 inch diameter steel rod stuck in a file handle, and with the last 1/2 inch or so bent over 90 degrees.
