Has anyone experienced the major interstate and other routes while displayed on the Navi screen being wiggly/jagged ILO very clear and definitive?? I just installed the new navi disc 10.1 on my 2007 LX hoping this would clear up the problem but it hasn't. Looking through the owner's Navi instruction manual I cannot locate anything that I recognize which may correct or cause this.

Please advise whether or not yours is clear and distinct with the roads. My ES is perfect but recognizing it is gen 5 so not the same.

Appreciate all.

I don't seem to have the problem you describe on my 2007 LX470.

I had a series of problems with the NAV ECU a year ago where it would go blank or tell me to insert disc. Lexus replaced the ECU under warranty.

Purchased the latest navigation update online from Sewell Lexus. They rock.

 

Thanks for the response. Glad that yours is fine. I have never seen anything like mine as I stated in my previous post. Have an appointment tomorrow am
with Lexus Dealer hoping that this frustrating item can be corrected. It almost seems as though it is reading intermittently from the satellites on a consistent base like this _____------____ (some short & some longer) plus being wiggly over the major roadways.

 

Hello Folks,
All of us that have the gen 4 Navi may as well get use to the screen as it is now. The Dealer advised me this am that this is normal for the screen to act this way due to the graphics. One gentleman was there that had an '03 LX and he stated his was the same way. Lexus Hq phoned me later on another subject and made use of the opportunity to advise about the navi system in the LX.
Stated she would check to see if it were possible to change the graphics card at my suggestion. I don't know if this system has a card but I'm certain there must be one to support the system. Probably will hear no more so I am going to enjoy my LX to the fullest.
