08 model Yaris. My flip down sat nav head unit decided to stop working. Worked fine on the way to work, hasn’t worked since.
Sounds like something is running inside, i have a blank screen and buttons, buttons light up every 2-3 minutes or so for 1 second. I cant turn it on during that second or operate any functions.
I can't flip down or tilt the screen. I've pulled the unit out and checked the wiring but all looks good.
Any ideas?
