On my wife's '13 RX350 F sport model, the HUD just stopped working/displaying. I've messed around with the three switches on the right side of steering column figured maybe the brightness is dim or it's position is off but didn't do anything. I also tried to locate the fuse for it but could not find the fuse unless it's called something else, I've only found two fuse locations under the hood and under the drivers side dash.
If anyone can help out that had a similar issue that would be great or if I've missed another fuse box location?
Thanks!

 

The fuse set in the engine compartment are like main fuses (rated for higher current). The fuse inside the cabin is for branch circuits. Branch circuit is when few things become inoperable while the main fuses if blown will leave many things inoperable,
