Man! Thanks for this video. For me it came a little too late because I bought my 08’ Z4M last year with the same problem. Checked in the forums and everyone said nothing but original won’t. And they are super expensive on eBay. So I ended up putting a CarPlay in the unit, but sacrificing the open/close mechanism
That's one of the main reasons I wanted to keep the original. I don't like that screen being open all the time. I saw another solution which utilized an older 6" garmin unit, but that was AFTER I already completed this project. Eventually, I might just swap out the dash for the one without NAV and install a double DIN unit.
@@CarGuy1 thanks! Eventually at some point I’ll follow your steps. Definitely would like to keep it original. Z4 units are too expensive. Awesome what you did!
Buenas quería saber si cuadra perfectamente la pantalla x3 e83 en el z4 e85 aunque no se pueda poner los tornillos traseros que sujetan la pantalla z4 e85 ? Un saludo y gracias
I don't believe it was just the ribbon. It's obvious that someone opened this thing up before for some reason and they likely damaged the ribbon during disassembly. I don't see how it would fail on it's own. The secondary fail was the gear on the electric motor. It was nowhere to be found.
@@CarGuy1 thank you for the response. I am dealing with a screen which will not power on and trying to determine if it is the screen itself or the nav dvd player. Do you know if there is a way to bench test the screen with a multi meter or aux power supply?
@@michaelgeer9371 You'll need to give it an input signal. Does yours flip up and stays black? Side note - make sure that your battery isn't drained. My car sat for a while. When I put the "refurbished" unit back in, the screen would flip up and remain blank. It almost drove me crazy. I then tried to put the convertible top down and it wouldn't move. That's when I charged the battery and everything came back to life.
@@CarGuy1 no issues with the screen movement and just installed a new battery last weekend, and put the top down with no issue. Found the wiring diagram for the 18 pin plug, it is receiving power and all grounds, and had voltage at the r,g,b pins which leads me to believe the video card in the dvd player is functioning. I got the Sharp video screen uninstalled today. Going to order a screen and hope it is not an issue with the circuit board. As a contingency, did you keep the board from your extra unit and would you be willing to sell it, it that is found to be my issue?
@@michaelgeer9371 I kept the board. let me know if you end up needing it. It's the original board from the E85, since I put in the one from E83 in. They did upgrade the E83 unit. You can readily tell because it doesn't have all of the capacitors that you see on the E85 unit.
@@dominik1307 Don't panic. LOL. Is your battery charged? Also, try disconnecting the 2 switches (the ones that open/close the screen). I remember mine doing something finnicky.

Any idea where to find one in good condition where the plastic isn't peeling? I can replace the LCD, but the soft-touch plastic seems to be an issue.

What ended up being the root cause of the failure? Was it the ribbon cable that was bad?
