The kit is for 2018 Open Road (there are other years available too) and during the screen set up you choose your floor plan.
The upgrade kit is here:
Instructions are clear and installation is simple. Behind my existing unit was the wall paneling with a hole drilled in it for the Spyder cable. You have surface mount or recessed option. Surface is the simplest, you remove the existing control, unplug the cable, mount the new frame on the wall per the instructions, plug the cable in and snap the new panel in place. When you power up, the set up screen appears and you choose your floor plan. You can also go to settings and choose the floor plan. Thatís it. There are other settings options also,...panel display, etc., in Settings.
For me surface was fine but a little close to the closed slide. To recesses mount you have to cut away a portion of the paneling which has a plywood backer on it at that location. A template is provided. A scroll saw and a drill was all I needed. There was a horizontal wood brace behind the opening but it easily clears the control panel.
You may not have that issue in your floor plan however, you may be able to adjust it on the wall laterally a little to provide more clearance for the slide facia.
I shut off power to the Spyder system by switching off the house batteries while changing out.
