Lexus SC430 :: Nav Screen Lighting / Dimming
Jun 22, 2014
Have a question concerning the nav screens lighting/dimming. If I'm correct, doesn't the nav screen appear dark with highlighted details, at nighttime & during the daylight, the screen is bright (white) with dark detail? The other night I got into the car & turned on the nav system. It appeared normal (dark screen), but suddenly switched to the light screen. I thought it may have something to do with the dimmer switch,but i turned it on/off with no change. Is there something that I may be forgetting to try or could it be the sensor that lets it know whether it's night or day? Also, is that the sensor located on the dash (passenger side)?

Just picked up a pretty nice 2002 sc430 today. On the drive home I realized all the dash backLights are not lighting up. However the The radio and climate control unit do have a dim backlight working but is stuck at one level of illumination.
Like most cars the all dash lights should be very bright during the day and when you turn on the headlights they should all Dim down. ..... Not on this SC.
Makes no difference what position the headlight switch is in....Nothing changes or lights up
and
The little Dimmer does nothing either when turned all the way one way or the other.
Fuses? I am not sure what to try.

I was just wondering if it is possible to connect iphone to the Nav screen in a 2002 sc430. Can the VaisTech do this?

Diagnosing different minor problems with my sc430. Tthe lastest one is that my navigation screen will not tilt back so the cover will go over it. It seems like its tilted forward all the way. The screen still works and all. But the tilt button does nothing and its too far out for me to get the wood grain cover to go over it. Is this a common issue? and whats the remedy?

Looking for info about taking the info/control screen apart. I have a very small amount of moisture that only shows under certain light conditions.

Unfortunately my car Heater A/C Control Panel LCD is broken, I mean only the screen. I accidentally hit the screen while I was pulling my guitar from the back seat .It shows many black lines that are almost covering the whole LCD!! everything is working fine except nothing can be seen on the screen.
I was told that I must buy the whole panel and it is really costly. I thought maybe I can replace only the screen? Is it possible? Or can I get any other car LCD and fix it into this panel??

Yesterday I noticed my nav screen stopped responding but partially. It'll let me press buttons on left side but not right side. Unfortunately the "I agree" is on right side so I can't even get passed that screen. I don't use the nav but I'd rather have the map showing then "Caution...."

I took my SC430 to the Lexus dealership to get my passenger side air bag replaced due to the recall. I decided to have them work on my car by getting the oil changed, replacing a dead foglight bulb and checking on my navigation system.
I told my consultant that the nav will not work after I press the "agree" button on the screen and it just freezes. Later on, tells me that there's something wrong with the ECU chip and.

Just bought a '02 Sc430. The navigation screen pops up but is unresponsive to touch input. I tried to search for a thread with this issue but couldn't find one.

I just got an 02 SC430 and I am going through a few things. The Nav screen works fine but is frozen in the rear tilt position. I would be okay if it were frozen all the way forward???

I own a 03 sc430. I want to be able to play music and view videos on my nav screen using my stock unit. I've been online for days and even talked to vais tech, they had a unit but i cannot view or control my music or videos with it. What I can use?

A couple of weeks back out of the blue my Nav screen stopped tilting back and of course if it doesn't tilt back the door won't close. I did the Lexus Diagnosis on the Tilt and Close Switches and it turns out to be something in the 'Nav' unit. Of course Lexus doesn't sell parts for the Nav unit... just the whole thing.
Since that time I have spent way too much time on diagnosing it and I actually tried another used unit that has the same problem as mine. What I think that I have figured out is that the motors are ok but the control unit, a small circuit board within the nav unit has failed. The problem is that this unit has 2-3 IC chips on it and any way to repair this circuit board.
Any luck repairing these circuit board or am I stuck.... The I was able to retract the unit into the dash and the door opens and closes but it would be nice if it tilted as they had intended...

Just took delivery of my 2005 SC430 (Egyptian Sand, white leather, 55k miles. Lovely vehicle.) which I thought came with Bluetooth.
However, when looking to pair my iPhone 4S the 'Phone' icon is not present on the ML Nav Info display screen, suggesting that maybe Bluetooth is missing? I confirmed it's a 2005 from the VIN.
When I depress the little button below and behind the steering wheel volume buttons (left side - this is a US car) I get a voice saying 'No cassette inserted' or words to that effect, suggesting it's a cassette control button, not a Bluetooth one. The Nav instruction book which came with the car specifically refers to the presence of Bluetooth.
How to find if I have Bluetooth or not? My iPhone cannot 'discover' anything.

I recently purchased a 2009 Corolla LE. I noticed that at night, my radio does NOT light up. However, when the car is in the 'on' or during the day, the radio screen is lit. I just know this can't be right. Is there something I can do to fix this backward problem? Or do I need to take it in?

Swap out the LED dome lights in a 2012 Camry SE? I'm considering switching the bulbs out from the yellow tone stock lighting to the white lighting LED bulbs. I am also considering floor lighting that can be activated with the dome light switch and/or with the doors opening. The issue I'm having is that I would like them to be hooked up to the same switch that the stock lights are set up with. (So I can use the dimmer switch for lighting). Where I would be able to tap into the wiring for this? Is there a DIY thread somewhere?

Last week I noticed my interior mirror was not dimming. It was turned on, the light on mirror was illuminated. So were the headlights behind me.

In the last couple weeks, once the car starts moving the Speed Dial button dims. Does this also on our 2013 RX350. I've had the car for a year and I can't believe that its been this way the entire time. I'm so certain it recently started. I had to revert to clicking the Call History button sometimes.
I feel it either corresponds to update to iPhone IOS 8 or iPhone 6. If that is the trigger, I'm surprised the Speed Dial is not controlled by the car vs the phone.
I was at Lexus service yesterday and they think its working as expected. Why would one not be able to click Speed Dial, but be able to click Call History and then taking eyes off the road to look at the screen and scroll to find a number!!!
One of the lexus folks was in the car and paired his phone that was an older iPhone and was not OS8.

Noticed the lights on instrument panel dimming as you accelerate? I'm talking about the very top of the instrument panel located above the speedometer. I'm driving home from work last night and as I accelerate I notice the blue tint light at the top of the instrument panel dims... let off the accelerator and the light brightens back up... switched the car over to "sport" and give it the gas... light remains constant, no dimming what so ever... switched back to "normal".. give it a little gas and the blue light at the top of the panel dims.... car seems to be running absolutely fine, no issues that I'm aware of... but I've never noticed this before.... and curious as to why it only dims when the car is in " normal ", but not when it's in "sport" mode and the light on the dash is red....

So one of my favorite little details is how the dash display switches from blue to red in Sport/Sport+ mode.
I was driving around today and noticed that when I pressed on the accelerator, the blue light would dim down to dark. I didn't notice it earlier and am wondering if it happens for other people?
