HELP! Factory Nav Screen went blank, and no radio.

I have a 2006 LE with Navigation and today when I started it up it was blank. When it is dark I can see the screen is glowing. I have climate controls still, but no screen. Also funny thing is that I have no radio or cd functions. WHen powered up I can eject the last cd played, and when I put the cd back in that cd will play. I can not shut it off, and I can not adjust the volume. Not even the steering controls will work for the radio. I have power everything so this is strange. Any ideas?

The precursor two weeks ago my BRAKE VDC OFF and SLIP LIGHT were on at times with start-up. Last week the lights went away. Anyone have an idea?

Just wanted to chime in that I also experienced this same occurrence today in my 2005 Titan. No display and no radio function. Cleaned the battery terminals as noted above and it fixed my problem also.

Edit: Thought it was fixed but alas . no. Worked the first time after disconnecting the battery but after that the screen went blank again. Hmmmmm

Fix Ever Found?

My 2004 CC LE just did this while driving. Playing DVD and the radio just shut off as well as nav screen. Climate functions still work but no radio/dvd/cd controls at all and no nav display — though it does look like the display is still being backlit. Did you find a fix for your issue?

The controller is shot and needs to be replaced. Because the backlight stays on after power off, you’ll need to address it sooner than later so you don’t come out to a dead battery every day . replace it or unplug the unit from the rear of the controller. I chose to unplug it and haven’t replaced it yet. You can find used ones on E-Bay.

Also you can search this forum for tips on how to remove part of the console/dash to get access to the controller.

Do you have a part number?

By «controller» do you mean the head unit for the radio (attached to the CD changer) or the control unit for the radio (the dash bezel with all of the buttons on it)? If it is the head unit that isn’t so bad since my CD changer stopped working last year and that comes with the head unit purchase from ebay. Did you fix your issue? Did you replace the head unit or the actual control panel (bezel). Based on what it is doing I’d lean more toward it being the head unit.

Anyone able to get this fixed?

Guess I’ll be resorting to dealership service soon but I thought I’d give a shout to see if anyone had any thoughts on this yet or fixed it themselves? I just don’t want the dealership to throw parts at it in trial and error fashion until they get something that works. That’ll be pretty expensive.

In may case the nav/radio doesn’t work most of the time and then on a random start-up it will come on and work for the duration of that ignition cycle — no matter how long I drive it. The display will work fine, all of the controls, etc. Then upon next ignition it will go back to not working again.

I am a leaning towards a bad ground, loose connection, or even a software issue on mine (it frequently comes up with temperature reading on the display and/or driver/passenger on the display) — both features of the Armada but not on my Titan.

Anyway, just thought I’d check if anyone has actually fixed this issue.
