    The touchscreen on my 2011 Prius with JBL NAV system failed and wouldn’t register touches. I decided to take a gamble and find a replacement screen and attempt the repair myself since a replacement radio is so expensive. Long story short … success!

    I have the JBL nav radio labeled E7022 on the plastic near the lower right corner of the screen.

    I removed the radio and disassembled it to the point where the touchscreen assembly could be accessed. Only portions of the front panel needed disassembly, I didn't have to go into the radio itself. It was easier than I expected, but I have taken apart and assembled electronics in the past. After a lot of searching, I found that the touchscreen was available for about $70 (from China). The specific touchscreen model number I ordered was a LQ070T5GA01 (7 inch panel for Toyota). The touchscreen is made of glass and is separate from the color LCD display which is under the touchscreen. Here's what the replacement looks like:

    I reinstalled the radio so I would be able to use it (albeit without the touchscreen working) while waiting a few weeks for the replacement screen to arrive. The screen arrived and I uninstalled the radio, replaced the touchscreen, reinstalled everything and it worked!

    The trickiest part(s) were the removal of the flex cables … the connectors that ‘latch’ the cables are small and somewhat tricky and can easily break if you push/pull on them the wrong way, so I was very careful in unlatching and removing them.

    I was very happy I saved money and learned even more by doing the repair myself. If it wasn’t for Priuschat, I doubt I would have attempted it. If you have some experience with electronics, you should be able to do the repair if your screen becomes damaged or fails. YMMV.

    Is this a black and white display?

    edit: Never mind. It's just the touchscreen that goes over the display.

    Thanks for the encouraging post! Would you be so kind as to share which videos/posts you found most helpful for the 1) dash disassembly and radio removal and 2) the touch screen removal and replacement? Thanks, Charlie

    Hi -
    Radio removal is easy:

    I didn't refer to any posts/videos for the removal of the front screen. I just eyeballed everything and began removing screws and taking things apart. It was a fairly simple disassembly. After the radio was removed with the display in the "open" position (as if you were going to load CD/DVD), I removed the large mounting brackets from the sides of the radio, then removed two clear plastic covers that allowed access to remove two ribbon cables connecting the front panel button assembly to the radio, then screws that held the front bezel on, then a few more screws that mounted the display assembly to the "arms" that move it ... Then you can remove the back of the display assembly and disconnect it from the radio.

    thanks for the post tgtech! I am stoked that I was able to fix my touchscreen on my 2011 Prius with the JBL E7022 stereo.

    I was able to find the part LQ070T5GA01 on ebay and I did order it from china. I used ebay seller xcar-parts. I don't think the part was brand new as described but it was in excellent condition and it was in good working condition. It did take about 2 weeks to arrive.

    The dash and stereo itself is super easy to uninstall. You can uninstall the stereo in literally 5 minutes. See the youtube videos. The wiring connectors on the dash parts and on the back of the stereo all have a piece that pushes in to release the catch and then you can just unplug. The round connection on the stereo is the antenna and it just pulls straight out with no catch. Once you get the stereo out then the fun begins.

    The black front piece that surrounds the front has some obvious screws to remove but there are two that are not as obvious. You have to remove the side mounting brackets to get a clean shot at the two black screws that are in the upper left and upper right corners of the unit when you are looking at it from back, right side up. So once you get the two black screws out you have to manually open the whole lcd/touch screen assembly so that you get the surround off. Manually open it by pulling it gently and slowwly outward at the bottom. Oh and before you do that flip it over front side down and remove the two clear plastic covers so you can access the ribbon cable on each side that connects the control buttons on each side. I forgot to this and one of the cables popped off but luckily didn't damage anything.

    So the hardest part of this whole repair is disconnecting/reconnecting the flex ribbon cable that goes from the lcd/touchscreen unit to the main stereo. You have limited access to it from the front of the stereo . Here is my biggest tip: the release pulls straight out towards you not upwards. It's hard to tell because you can't really see it very well. So don't pry it up from mother board but rather gently pry each end toward you in what would be the same direction that the cd pops out. I used a tiny screwdriver to pry each end a little a time untill the cable was free. I also disconnected the LCD assemby from it's pivot points first so I had a better view of what I was doing. Pushing the geard frame thingy back down and out of the way helps also.

    Once you get the cable free the whole lcd/touchscreen unit is free of the main stereo and you can go to work on it. Pretty easy from there.

    So to continue my story, I undid the screws on the back of the lcd/touchscreen unit and there was another place where the main ribbon cable was attached. It has a silver lift type attachment which easily opened and release the touchscreen from the LCD. The touchscreen itself has a small ribbon cable with a pull-straight-out type connector and what looked like a wireless antenna attachment that pops straight up and off.

    Anyway I put the thing back together and reinstalled it in the car. When I powered up the actual LCD was not lighting up. Ugh, major disappointment. I had fixed the touch screen but broken the LCD. I knew the touchscreen was working because I could now open the front of the stereo by touching the place on the blacked out LCD screen where the 'open' button should be. Things had gone from bad to worse....

    So I check the connectors on the back of the stereo and one wasn't clicked in the whole way so I'm crossing my fingers and turning it back on but alas, no LCD. I could listen to the radio and all, just no display.

    So I pull the whole thing and take it back to my workbench, go through the whole thing again, thinking I missed a cable or something, really knowing the whole time it's gotta be the main cable. I thought I must have damaged it when I was prying on it the wrong way...thinking crap this has gone sideways on me....

    I put the whole thing back together again and re-seated the cables and made damn sure the main cable was seated as deep as it could go with the connector firmly pressed back down. I re-attached the stereo connectors.... by this time it's 9:00 at night and I'm working in bad light, pretty much doing the stereo connectors by touch, which was actually easier than trying to see what I was doing...funny. Anyway I get the stereo back in and IT LIGHTS UP! Hooray, the LCD is working and the touchscreen is working, but wait a minute, now a big orange triangle with an exclamation mark is showing up on my dashboard telling me to 'check hybrid system'. I don't think there's anything wrong with my hybrid system, it's probably because in my haste to test the stereo I was connecting only the part of the dash panel that had the 'power' button... so I drove the car to the end of the block and back to test it and it doesn't go away. As I'm driving back somebody is walking out in the street and walking straight at me. It's dark out and I'm driving kinda slow. The person is walking like, straight at the driver directly in front of me. I'm thinking it might be my 12 year old daughter who I was supposed to tuck-in a half hour ago because she looks kinda pissed; she's got her arms folded across her chest, but it can't be my daughter, she knows she would be in big-time trouble for walking around in the street at night in traffic...so this mad lady walks up to me and as I roll the window down she asks me angrily, "Why were you parked in front of my house staring at my daughters?" So I'm like, "oh, I'm your neighbor I was just trying to fix my stereo" and I went on to explain the whole touchscreen repair endeavor. So she apologizes and we laugh about it. I haven't had the Prius that long I guess she didn't recognize it. I guess I had pulled out kinda in front of her house and I was staring at the orange triangle of death on the dashboard, which probably did look like I was staring out the front window.....LOL, I was oblivious to anything other than the challenge at hand, anyway...

    So back in the house I go to do a little more googling and I find that if you hit the power button a couple of times with your foot NOT on the brake, it may clear an error of this type, and yep, it works. The orange triangle has gone away. Hooray. Everything works now and I only had a few close calls, three if you count the neighbor.

    That's great! Congrats and those are excellent details for others to know if they want to replace their screen.

    One item I forgot to note was the new touchscreen I received had peel-off protective film on BOTH sides that should be removed before installation. I was a little worried the plastic was part of the screen itself, but it wasn't.

    Thanks for posting! Good timing since the touch portion of my display recently stopped working, hopefully I'll just need a new touchscreen as well.

    Thanks @tgtech! The whole operation was easy, thanks to your posts. It would have taken ten minutes less if I had remembered to reattach the two ribbon connectors that carry signals from the radio buttons to the circuit board before I put the radio back in.

    @CharlieT - That is fantastic! Congrats on the repair and saving yourself a bunch of money. I hope this thread will help people get the courage to give it a try if their screen is scratched or broken. Everyone's contributions help! I don't know if it's a placebo effect or not, but the LCD behind the touchscreen seemed noticeably brighter and crisper after the replacement which was an added bonus for me.

    Thank you to the previous posters. I finally received the touchscreen and was able to successfully repair my Nav unit. I took it slow and followed the instructions above - nothing else to add except once you remove the screen from the main unit you do not need to remove the large ribbon cable, just work around it.

    I am about to start the process, This was the best info ever!

    Went to the car wash and the roof blowers on the roof blow forward and water hit the small gap above the screen!

    First, Thx a bunch for posting this. My 2010 Prius IV JBL touchscreen failed this week, and i'm now obsessing about it.

    I was thinking the issue was related to connectors. My touchscreen registers some touches, but they are in the wrong place - some "regions" are active, most are dead, and the ones that are active go to the wrong location on the screen.

    I'm definitely going to look into this replacement.
    But i have a question...
    To "open" the display (load CD/DVD), it is a touchscreen function. How do you put it in "load" mode if the touchscreen is not functioning?
    Is it necessary to put the display in the "load" position to get at the display?

    thx
    -jeff

    With power on, press and hold the "Close" button for about 10s, then release it. Your failure symptoms are almost exactly identical to mine, so it is a VERY good chance it is simply the display touchscreen.

    tgtech, great to find your post! My 2011 Prius Nav Touchscreen cannot register touches as well. However, every physical button around the Nav Touchscreen is okay to use. Do u think it is the same case with you? Thanks a lot!

    Success!

    However. Is there protective film on the inside side of the new panel?
    If so.. i missed it.. it was hard to tell. I think i might have installed the new panel with the film still on the inside. Hm.
    ( I did remove the protective film from the facing-out side of the replacement panel. )

    I do wonder if this is doable w/o removing the radio from the car.
    It seems the panel could be put in the "load" position, and the two screws on the "arm" removed, then the ribbon cable removed.

    Fwiw, i didn't remove the "large" brackets.. there was a hole that i could angle the screw driver into.

    The ribbon cable connector from the panel to the main unit was baffling -- I read Schrap's writeup a couple times and then flicked the connector on each side toward the "front" of the radio (NOT up, which i initially tried).
    Same for the one under the LCD panel cover. It was tricky to get the connector fully open.

    To get the panel out of the "motorized arms" i had to a) remove the screws, and b) spread the arms a bit gently (one at a time).

    I think there should be a dab of locktite on the "motorized arms" screws.

    It didn't take that long.. probably about an hour to remove and re-install. I was surprised.
    Getting the dash panels off was difficult -- i used an old drivers license initially, but ended up mostly using my fingers with a gentle "pull" at each snap-in bracket point.

    When re-installing the dashpanels i took the opportunity to clean scum out of the cupholder, and dust from the shifter area.

    I also got the "yellow triangle , hybrid system error". I think this is because i turned on the car with the "parking brake" button disconnected (when i was testing the radio.)
    So, I simply held the car start-button down for 5 or 10 seconds and the yellow triangle disappeared.

    Its nice to be able to adjust the audio again.

    tgtech - thx for the initial post on this.

    My touchscreen just went wonky too. Has anyone tried replacing without removing the whole radio unit? I took a quick look with the screen open on load function and it looks like it may be possible to do this without removing the whole radio. I just ordered my replacement, will have to wait like two weeks for it to get here though.
