I've recently installed PMR's (radios) on my GoldWing and on Joanna's Spyder so we can communicate when out on rides here in the UK.
My research indicates that many people have tried to make use of the Press-To-Talk button which Can-Am kindly provides on the RT, but all have given up due to it being on the CANBUS. I too was desperate to use it, but when I dismantled the left hand multifunction switch clamshell I found that the leads coming from the PTT switch are on a flexible printed circuit board and are extremely thin - so I too chickened out.
However, I didn't want to use a switch inside a box stuck to the shell, as others have done, so I managed to install an extra momentary contact switch in a hole drilled (carefully!) in the clamshell. I then ran the wires from it down the inside of the handlebar shroud.
I thought it might interest others, so I have attached some photos.
