Hello I have 2007 prius. While driving down from Toronto to New York, something happened to the MFD buttons. Since I did not have an updated map, we used an another hand held GPS along with prius GPS. My friend put his hand held GPS on the MFD screen using the suction cup that comes with his GPS. After we reached the destination, he took out his GPS and in the process, scratched the MFD screen. The scratch is minor. The next morning when I tried to put in the address, some of the touch buttons on the key pad of the MFD did not work. I tried fan speed in climate control but only the button for Medium, and last two High speed would work. Temp. control "up" and "down" works fine. Audio, again I can only change 2-3 stations and on C.D. changer, I can only change 3 C.D`s. The trip information screen is displaying properly and the back-up camera is working fine. I took the car to a dealer and they are going to take out the MFD screen and send it in for diagnostics. Is there any thing i can do at home to rectify this problem. Thanks.
I hope you don't mean you actually suctioned the cup to the screen. That could have pulled the different layers apart that make the screen touch sensitive and would make the buttons in that area un responsive.
yes unfortunately, he did suctioned the GPS on the screen. Looks like I have to get a new MFD. is there any other way to repair the screen???????
The screen could be damaged is it a scratch or is the glass under the overlay cracked? John (Britprius)
It is likely that the vacuum behind the "suction" cup has separated the touch screen overlay. Try warming it with a hair dryer and the pressing on it with a cloth folded to form a pad. I have on two occasions repaired touch screens in this way, but no guarantees. Failing this a replacement off Ebay or a breaker. I know to late for you but nothing should be attached to touch screens. John (Bitprius)
