Each side is tuned perfectly, if you take them off you need to mark them to avoid any problems.
Here is a shot of the cab. I pulled it under the cowl on the passenger side. The I used a small piece of aluminum to mount the holder to, and just used double sided tape to mount it out of the way on the side of the nav system. No holes.
You could run the wire on either side of the console and mount the handpiece where ever you like.
