Hello all,
I’ve had my 2009 GS350 for 5 years and just noticed this **** in the trunk (shown near the center of the image). I couldn’t find any info on it after some brief googling. Does anyone know what it is and what it does? At first I thought maybe its a subwoofer controller since its right next to the sub, but turning it didn’t seem to affect sound. As it turns it either gets looser or tighter so I figured its not really a **** with a function. I didn’t bother taking it all the way off. Any insight would be appreciated! Thanks!

 

It is just a screw to hold the trunk lining on
So it doesn't do anything
