Has anyone ever seen this triangle shaped box affixed to the windshield? I have had over 100, 2004-2009 Prii and have never seen this. It looks factory.
Rain sensing wipers? Hmm, maybe not, I don't know if that would be placed over the dotted area as I would think it would affect sensing the rain drops.
I have the Hybrid battery out of it now until Monday so I don't want to power it up now but I was thinking it might be an XM antenna. They are usually mounted on the right side of the dash and look like a roach motel.
Damn that's big for an xm antenna, or at least looks big in the pic. When I installed a plug and play Sirius radio in my 2006 many years ago the antenna was tiny, like the size of a quarter to maybe inbetween a quarter and half dollar.
