    Not for a newbie. I unplugged bottom cable and unable to reconnect. My touch screen is now dark and unable to see what radio station tuned to or see map. Where can I find replacement unit that slides out? Is that the NAV head or entire radio??

    I just created a youtube video from my experience of replacing the touchscreen on my 2011 Prius with the JBL Navigation unit. Thanks to everyone on this thread for giving me the confidence and guidance to spend $80 to fix the problem instead of going to the dealer and spending a couple thousand to replace the whole unit. I thought I would give back by making this video and posting it for everyone. Hopefully it will help someone else in the same situation.

    everyone. Wife's touchscreen works fine but LCD looks like it's going. Don't have a photo right now but it's nearly all white and the letters/icons are mostly swirly rainbows. Any suggestions? Any posts in Prius Chat you could recommend? Haven't found one yet.

    Thanks! :)

    Nifty! Looks like fun. :)
    It would have been nice to see HOW you were able to finally get the last cable back in.
    I guess you needed 6 hands to do that? :)

    Any thoughts out there? I just replaced the touchscreen on my 2010 Prius. I have the same failure as above. Radio works but nothing on the touchsreen responds. Digitzer replacement completed with no issues, but still have the same issues with no response on the touchscreen even with new part?

    Any thoughts or suggestions? Bad part?

    Just purchased a 2011 Prius with unresponsive touchscreen. Fantastic instructions. Everything went as you described. Took me 30 seconds to get the last cable in. Just hold the screen horizontally with the upper edget sitting against the back with my left hand. Placed a portable worklight to see what I was doing. holding the cable with my right indes and middle finger, was able to guide the cable into the slot. Then it's just a matter of pushing the lock back in place. It's so nice finally being able to adjust the brightness of the screen so it's not stuck in the day mode blinding myself at night.

    Got a little motion sickness from the video tho. That's just me... I throw up playing first person shooter games....

    Replaced my touchscreen and the touchscreen now works fine. However the on/off, Close, AM, Tune and up seek buttons do not work. Consequently, I cannot close the screen automatically and am afraid to try to close it manually. Unsure I can get it open if I close it. Any suggestions? Is maybe one of the cables not in right?

    Now additional problem. I came inside to research the problem and I guess because I turned off the car and closed the car door, sometime after it closed the display and since the close button does not work, I cannot get it opened again. Any suggestions how to get the display open if the CLOSE button does not work?

    Thank you all for your detail instructions. I revived my 2010 Prius MFD a couple of weeks ago. Special thanks to tgtech for his instructions and answers to the members; llluminus's discovery that we could take the multifunction display (MFD) out without taking apart the rest of the stereo; Duck Pants for his more detailed instructions. Last but not the least, joniowa's detail step-by-step video that basically cleared up my concern about the ribbon cable.
    I just want to share my experience of the MFD screen replacement with other members. The $80 dollar screen does work. However, I think the glass is thinner than the OEM ones. May be that's why it takes just a little bit more pressure to register each press. I would advise therefore not to press too too hard at all times to avoid cracking the screen. The seller and other members have already warned us this glass crack easily. That said, being gentle in handling and using it should pose no problem.
    I took almost 2 hours to complete the replacement because I just want to be very patient. Removing the MFD from the head unit sliding guide, I used a PH1 size screw driver. Using joniowa's video, I noticed his placement of the MFD after taking it out of the guides is the best way to access the ribbon cable lock. In reality, in that position the access is quite good. The locking mechanism is not deep inside the opening. BE SUPER PATIENT. Rock the latch towards yourself from side to side, a little at a time. The ribbon will basically slide out when unlocked.
    I used PH000 size screw driver to remove all 8 "blue-circled" screws. After opening the metal cover (through which the large ribbon cable goes through), I had to release the other end of the ribbon cable from the motherboard. I tried to rotate the metal locking mechanism to release. That took me a while because as I was pushing the metal bar up, it came loose but would not lock at the 90 degrees position. The metal bar was just loose but the cable would not budge. I did not want to break anything so I didn't force it. It turned out that I did have to apply a little force and it will lock in the 90 degree position. However, I made sure to hold down the rest of the locking mechanism to the board so the upward motion would not end up pulling the entire mechanism off the board.
    I used a PZ0 size screw driver to take out the 4 screws holding the board and LCD to the black plastic casing. The rest is actually quite simple, ..., until I tried to install the new glass. Finding where to peel off the plastic from the front side of the screen took me a while. It does not appear to have any plastic cover, but the posts and seller's instruction say there is. I did not want to damage any of the "wiring" on the glass. I noticed there is a little bit more space on the side where the digitized cable is and so I started from there. Having not cut my fingernail turned out very useful for this process. Basically I scratched from a corner near the cable and lo and behold, there really is a piece of plastic there. LOL. The plastic on the other side of the screen is very noticeable but it is much stickier than the front side of the screen, so take your time, pull a little bit at a time.
    Reinstalling is straightforward. The four screws holding the board and LCD should be tightened evenly, snug is good enough because you do not want to break the glass. Reinstalling the ribbon cable to the head unit took me a while too, but finally got it back in. Although I did it myself, a second pair of hands at this point would probably make it easier and less likely to damage anything.
    Hope these pointers help. Good luck.

    Upon further reflection, I do not believe it is necessary to remove the large ribbon cable from the motherboard. So IMHO, this step is optional. Just be careful when removing the LCD/motherboard unit from the black plastic case, mindful that the large ribbon cable is still attached to the metal case/cover. In other words, only two things need to be disconnected from the motherboard, the antenna and the digitizer cables.
