Sure Rich I would not bother either it is a fairly safe procedure if you follow the instructions carefully

Also there is a backup procedure to follow just in case you do make a mistake... Main thing is to have well charged batteries and unpack the files and then place them on a flash card the camera will recognise the right file before it will attempt the update..

if not any member who feels unhappy a local canon service center can do it for you.. In the case of the 5D is was worthwhile as it fixed one issue I had with some of my equipment
