Navigation System quit working.
We own a 2005 LS 430 with Nav. Today it was working fine then a screen showed up saying Please Insert CD.
Then some japanese writing below that.
I do not know where the CD to the Nav is much less what to do.
Any directions from someone?
For the navigation to work the car must have the cd in it. The navigation ecu is located in the rr of the trunk under a bunch of the carpet I believe. If you have never had the cd replaced for a newer one, there shouldn't really be a reason it shouldnt work, the ecu has a door you have to slide that uncovers a eject button to remove or insert a new cd. I have seen the ecu's go bad from time to time and have to have them replaced. A dealer should be able to spend minimal time looking at it and diagnose it.
