You have exposed terminals and wires on the back, I would be concerned about damaging them.
Not to mention the fat ugly wire.
I installed one where my old one was, drilled out the hole, nice install.
Is there anywhere else you can think to mount it?
It doesn't have to be right on the helm.
Oh, your Clarion stereo remote will work with it too!!!!!
Just aim at the CM-1 and zap!
