My wife was driving around today and the navi screen/audio blipped out. Navi screen went dark like it shut off, then came back on seconds later booting up with the Lexus logo....

I'm really hoping this isn't a major thing....Anyone else experience this? btw, 99 GS400 with Feb 99 HD update to navi...

TIA!!!

edit: I should mention that everything else in the car was working fine..ie no cel, gauges still on, car ran fine, no dip in power or surges...just audio going out, screen turning off, then coming back on and rebooting (3x).

bump....noone has had anything like this happen to them? =(

could be the harddrive going bad,could be the amp, could be the screen alot of different possibilities here

is the hard drive linked to the audio? ie if the hd went dead, then we would lose audio? screen seems ok otherwise..just based on how it works now, it seems ok. Where would the amp be? And would that actually cause the screen to blip out too?

im thinking the screen blipping could be a problem with the screen....although i would think if it came back on and reloaded the lexus system it might be a nav ecu or harddrive in your particular car. although when i detached my nav screen and plugged it back in the system reloaded. u recently have any audio or any other kinda work that would be in that general area

nope no audio or navi nothing...it just happened one day when my wife dropped the kids off at school, she said it happened 3 times on a 10 minute trip, then twice again on the return trip, but hasn't done it since....where did you plug the screen back in? maybe it's just a loose connection that got dirty over time?

thats what i was kinda thinking but i dunno.

screen plugs in from the back

ouch..so i have to take the dash apart to get to it huh?

for some reason I thought the HD was in the trunk, but i looked in there and it's not there...is it in the glove compartment?

i dunno, my car doesnt use a HD my NAV ECU is in my trunk and no, u dont have to take the dash apart, just take the shifter console out, ashtray, and unscrew the nav unit

u can follow from post # 27 in this post to see how to remove it.

You come to my rescue again sakataj!!!! Hopefully it'll be as simple as that...

If not, I have a harddrive and headunit for sale.. updated to 2001!

again? what was the other thing?

i forgot bout that....if it turns out to be the HD or HU u can buy his old one
