Hey.
Has anyone installed afterwards electronic rear window shade?
An impossible idea?
What about whether a coded fog lights to work lights in the turning angle?

 

I just use tint

 

Have never seen an aftermarket rear sunshade. And since the factory one is hidden when not raised, and it is motorized, I would think this would be tough to do. Tint would be the alternative as mentioned by the NikonGuy.
