I owned a 2008 Lexus IS350 and recently the touch screen of Navigation system does not respond (the GPS still working). Since the dealership fix cost at least $3000+, I bought a replacement touch screen from ebay (see below link) for $240. Then I follow the instruction that I found online (fairly easy) and DIY fix it. Now I am enjoy touching my screen of my car again.

Thanks for all the resource that I found, hope it helps.

 

Out of curiosity, does it fail after certain mileage, or age of the car. I have an 08 with 28K miles and I hope i don't run into this problem. But i bought car from old guy i don't think he was messing with the display much.

 

I never touch my display and mine failed.

 

I had an 06 with 110K on the odometer and it was working fine...i wonder what it is that cause it to fail? heat? excessive use?

 

Electronics could fail at anytime with unstable current. My touchscreen failed after I took my car to do a state inspection.
