I am drawing a blank (pun slightly intended) on the name of the plastic piece. I got it from a stereo installing shop. Its plastic and cuts pretty good with an exacto knife or box cutter. A din cover plate or ? Since I installed it, its been held in by putty. It pops out when it gets warm. I thought of a single torx bolt in the middle and have it anchored with a nut on the back of the cubby. But I will sometime soon do the Starkey products rear lights and move it to the left side dash area like they have it in their video.

I hope that helps...

 

Got a link for those switches?

 

The. starkey system is really nice. Watched the install video yesterday. Now I just need to convince myself that I need backup lights...
