Just looking for advice from the forum regarding the Nav screen in my 2008 LS600hL. Last year, I had the Prestigious Society bypass installed my local Lexus independent shop, and everything has been working perfectly up until just recently. For some reason, the display is shutting itself off automatically, going completely dark. I can easily bring it back to life by pushing the Audio or Menu button, and everything seems to be working as it should, but it's just weird how it's going dark. I'm not sure if it's related to the PS bypass unit, by something going wrong in the screen itself, or by some sort of automatic setting that has gotten inadvertently changed recently (to tell the screen to shut off).

Has anyone else experienced this screen shut-down issue? Any advice? The car is still under the CPO warranty from Lexus, but I don't want to take it to them for diagnosis with the PS module still attached (they may claim that voided the warranty on the screen, which would be BS). I'm hoping it's just a setting that has gotten messed up somehow. Thanks!

 

Sounds like you hit "Display" and then "Screen Off".
If you push "Maps" and the maps come up, does it stay on for the entire duration after that?

 

I think there was a thread on this before and it was linked to the PS setup. Try a search, or contact PS.
