well looks like there is a glitch and a lot of people are affected. navigation screen reset, not sure why but some glitch is happening. just wanted to post this so people would know your not the only one or alone. hopefully it gets resolved soon

 

from what I have heard to fix the problem you will need to disconnect the battery which is located in the back rear quarter panel in the trunk, it is in the corner

 

Hi all,

Having replaced my wife's prius battery, I'd really like to avoid doing so to correct the nav system. Can't you just pull the associated fuse to reset the nav system?

Does anyone know which fuse does what?

Thanks! Will.

 

I just did it on my 2015. Took me about 10 minutes. All settings seem to be there.

 

did you disconnect the fuse or battery?

 

I disconnected the battery.

 

No problems with 2011 version

 

this only for 2014+ models of all lexus vehicles from what I have heard so far.

 

finally was an issue for my mom, so I tried a few things and nothing worked disconnecting the battery seem to fix the issue.

 

Just go to a dealer, disconnect the battery negative terminal 10-20minutes.
