OEM nav screen repair/replacement solution

I haven't seen this mentioned anywhere, but if you want to retain your original nav screen, I found a pretty cheap solution. As I discovered, you CAN swap in the screen from E83 and it's not too bad of a process.

I suck at making videos, but here's how you can fix your screen without spending $1500+ on a used replacement unit. Technically, this isn't a fix, but a retrofit of an (almost) identical unit from E83, which can be had for much cheaper. If you are somewhat hands-on and don't feel like watching the video - here's the jist of this project:

• Remove the E83 unit from the shroud/surround. Easiest way to do it is to pry off the back cover. You will need to disassemble the whole unit to get the screen out
• Install it into the E85 shroud and re-use the E85 back cover. E83 cover will bind
• If your electric motor is broken - cracked mounting bracket, broken mounting post on E85 shroud, missing/broken gears - you will need to swap in the E83 motor. You will need to unclip the mounting bracket from the E83 shroud and bond it to the E85 shroud.

***I also found it impossible to find a replacement gear for the electric motor. The one on my E85 unit was nowhere to be found and the one on the E83 unit had a hair line crack. I reinforced the gear by gluing a small nylon washer on top of it. I did not outline it well in the video, but this seems to be a sound solution. I tried a number of adhesives and the one I found to work best was Visbella EasyFix that you can get on Amazon. I tested it on some spare/broken parts I had laying around and this glue is incredibly strong.

Comment below with any questions and I will do my best to answer. Unfortunately, my video did omit some parts that may be important.

Very very useful information. My E85 screen is a bit dim AND one of the hinges has broken. If I understand correctly, I should be able to get a used E83 nav screen and the only thing I would need to do it replace the shroud? No need to open the screen assembly itself, etc, but still put the back cover of the E83 screen needs to be popped out and replaced with the one from the E85? The hinges, motherboard, motors are left as in from the E83, right?
(Would like to make sure before spending $$ on a used E83 unit.
