So I bought my 2010 toyota prius V about a year ago. It came with a Built-in digital compass and garage control panel on the rearview mirror. All was well until one day I noticed that the digital compass turned off and no longer showed my current direction. The garage buttons seem to work fine - whenever I click them it prompts the small red LED lights on the panel. I've clicked the power button on the mirror but the compass will simply not show. How do I got about fixing it? Plus how do I locate the fuse for the compass, it doesn't seem to appear on the manual.
