is navigation screen cover replaceable?

[eujiji]

The case for the navigation screen on my z4m has gotten badly scratched. I was under the impression that the whole screen was only sold as a (very expensive) unit, but from realoem it seems that the top plastic cover is available as a separate part:

Is this indeed the top of the nav screen? If yes, is there a how to anywhere for how you remove the old cover and snap this one in?

You may not need to do that, here’s why.

When I bought my E70 X5 a few years ago I noted that the previous owner had scratched up the screen quite a bit. Apparently though the scratches were primarily to the anti- glare coating on the screen. A guy on the X5 forum suggested a Novus plastic polishing kit which I tried and it worked perfectly by removing the scratched up anti glare coating and leaving a nicely restored screen. I only needed to use the cleaner (bottle No. 1) and none of the other two polishes. I wrapped the cleaning cloth around a kid’s eraser to reach into the corners of the screen. You can find this on amazon :



Update. When I scanned your post I stupidly thought that you meant the screen was scratched but I see it’s the case instead. I’ll leave all this here in case you think you could use this kit to repair the case .

Thanks Huz-Z, indeed was looking for some instructions on how to swap out/remove the top case for the screen.

With some more searching, I have convinced myself the top is separate, but I'm not sure if it's possible to do it without completely removing the whole assembly (with the risk of damaging more stuff than you fix!...)

It's not impossible to remove without removing the screen, but the tabs are VERY easy to break. Easier to remove the screen: remove the vents above the stereo, remove 3 (IIRC) screws that hold the screen in place, and the whole thing pops out. You'll notice that the bottom part is actually two pieces, which once removes give you access to pop the back of the screen very carefully. To be honest I have opened 3-4 screens in the past and only once did I finish it without breaking any tabs.

Edit: In addition to the 3 screws under the vents, there are 3-4 more in the back of the unit that should be removed (under the trim piece behind the screen).

I have 2 full NAV systems if you need a replacement.

Thank you! My screen is scratched up/ugly. Did you put a new protective film on your screen after cleaning it? If yes, what did you use?

I’m glad this was helpful info! Nope I didn’t apply a New protective film after removing the scratched up anti- glare coating. That’s because the anti-glare layer doesn’t provide much protection and the screen looks almost brand new anyway. By the way, I did this about 3 years ago and the screen still looks just as good now as it did when I first cleaned it up in summer 2017.

Cheers!

Thanks for all the replies! Will attempt the replacement and post any useful pictures/guide if it works out...
