I went to the local Lexus dealer and bought a New 9.1 Generation 2/3 DVD GPS Update for my 2002 Lexus SC430. I got into my car and put the key in the ignition turned to key to ACC so I could power on the DVD & GPS System, went back into my trunk and took out the old original GPS DVD (OEM 2.1) that came with the car. Then I put the new 9.1 upgrade back into DVD and watched it load and update.

Problem now is the DVD Updated my software to Ver. 9.1, but I'm not getting the full functions out of my NAV Screen or DVD. My address screen is grayed out and it doesn't allow me to select my region on the Map either. The upgraded maps are there but it doen't allow me to enter an address or use any of the other funtions on my touch screen. The car is parked in my driveway and I even tried at work????

Does anyone know what I can try???? Tried to re-load the DVD Disc again, cleaned it with the lens cleaner, unplugged the battery cables for 5 minutes and tried again, but to no avail.

Any help will be appreciated.
thanks

The same thing happened to me when I updated from 2.1 Version to 8.0. I still to this day have sporatic problems with entering the addresses for destinations, When this first happened to me I did the same thing but I took my air compressor to the back of the trunk and opened the DVD player and blew compressed air into the player and that seemed to work. You might want to try that, it might have dust particles in between the head and sensor. If that doesn't work you may need a new DVD Unit. Good Luck.
