2013 Prius FIVE - Head Unit went from working/looking brand new to DEAD! Fuse OK - Power to/from Fuse OK. Hoped for an obvious loose wire - I see none. My wife started out and just a black screen. Nothing seems to work from the head unit (if I call it the right name?) Radio, GPS, DVD (even the screen drop-down for the DVD), nothing at all on the unit seems to have power. So, I am looking for the power source for the unit - hoping I can find an easy (ier) fix. Thanks
