I noticed on way to Florida that my tilt function on the navigation screen does not work. Has anyone had this happen? Is there a fuse for the tilt motor or relay? I have not yet started to check it out.

There is a motor. Usual suspect in these failures is the motor or misalignment on the track arm. But it could also just be the "tilt" switch... there have been thread on this issue in the past, so you may want to use the search function/ Advanced Search and limit it to the SC430 thread...here's one for example RADIO DOOR STUCK

Check out my thread on first page. I had the same exact problem - had being focal word. Took it apart last night and was an easy fix, door was off track.

Good day. When you say take it apart, what do you mean by that? Also was it easy to get to?

There are some nav screen pictures posted here

You will need to remove the two vents on either side of the screen...look inside the vent and you will see two locking tabs that you must slide out...

Then remove the a/c control

Now you should see two screws and two bolts that hold the nav screen in place. Remove them and disconnect the electrical connectors on the rear of the unit.

Check all of the screws on the sides of the nav unit. They are likely to be loose.

Thank you for the info. I will definitely give this a try.

This has been an ongoing problem with sc430 Navigation systems. Last year (2015) my lexus experienced a failure of the tilt mechanism. I purchase a used Navigation system and replaced my system. At first, all seemed well but with a week or so the same problem occurred. Bummer, so I replace the air conditioning control, bought a used one and replaced it. No joy, so the problem was not in the air conditioning control. Next, I replaced everything back to original and suddenly everything worked for several more weeks and the tilt failed again. Possible that both Nav heads had the same problem? So replacing the Navigation display head and/or the air conditioning control did nothing. I have checked cable loom and all seems good. Grounds and Power are good. This might be related in some way to another system, of which I can't figure out. Next, I'm going to bite the bullet and take it to the dealer and see what they come up with. Any Lexus techs out there with any ideas?
