A:Answer You can, I have done this in my truck. What you have to do is connect to rocker switch to a separate cigarette light power port available from autozone,(see image below, just cut off clamps) then plug the garmin power plug into that and hide it in the dash somewhere. I have mine wired to a switched 12 volt source (cruise control fuse) so it comes on when I start the truck. I have a Garmin in each of my trucks, so I'm not worried about it not being removable.
