The touch screen on my 2006 GS300 just flashes the Lexus logo repeatedly when I start the car, and won't let me get to any on the on screen menus. Any suggestions on a fix? Is there a way to do a hard reboot on the touch screen system. Thanks!

 

Try Disconnecting ur battery for 5min... If that doesnt work, take it to the stealer, I mean the dealer!!! Hope u still have Warrenty!!

 

That or maybe if there a fuse for the NAV that you can pull out and put back in to reset it. Never heard of this issue.

 

ouch,,hope u cant fix the problem and let us know what was the problem,,,

 

Thanks for the comments. I disconnected the negative terminal on the battery for 60 seconds and then reconnected. Touch screen returned to normal functionality when I restarted the car. Appreciate your counsel.
