This is a guide on how to replace the touchscreen on a Mazdaconnect infotainment system.
This guide involves some basic tools and a $15-$25 part from Aliexpress. It is significantly cheaper than having a dealership replace the entire CMU ($1500+), or DIY replacing the whole screen assembly($200).
The problem: Repeated hot/cold cycles causes de-lamination of the adhesive used to combine the touchscreen cover and the digitizer. This failure was a manufacturing defect, and newer vehicles produced by Mazda do not have this problem.
If your car is experiencing any of the issues seen below, this operation may be required to resolve.
If your car is still under full warranty, you can get it replaced at no charge. Info
Note: I took these pictures while re-assembling, after fixing my screen. If something doesn’t look right, let me know. Certain steps in this guide must be done with extreme caution to not damage the screen PCB. If you are not comfortable with working on electronics, do not begin this guide.

Thank you so much! I have a 2016 Miata and happened to stumble upon this guide, followed it, and now the infotainment screen looks brand new and feels so much better. Kudos to you!
This is excellent work. It’s not a complex process, but you reflect a fairly high level of skill. Thanks for the effort!

Does your touchscreen work without putting glue between your casing and the digitizer?
This great thanks. When you took the old one off, in the picture it seems like a fully glued surface. However, you don’t mention any similar covering of glue on the eplacement, just the edge?
The part you can buy from AliExpress is both the screen cover (the part you touch with your fingers) and the digitizer. They are glued to each other, but there is also adhesive sticking that assembly to the touchscreen bezel. The replacement from Aliexpress has both the screen cover and digitizer already glued together, and includes 3M tape that lets you stick it to the bezel.
Merci beaucoup pour votre tuto, excellent vraiment, j’ai changé la vitre sans aucun problème 👍

Just carried out this repair to our car and it looks like new again!
Brilliant, thank you so much.
A thoroughly excellent and very well-written and documented ‘how-to’ guide – thank you very much!
My car is a 2016 UK model, afflicted by the same spidery snowflake screen blemishes, and (out of warranty) my dealer had offered to pay the first £600 of the replacement bill, with me having to fork out £900 – it’s plainly a completely ludicrous and unnecessary exercise to swap out all that hardware for just a simple piece of faulty glass / plastic lamination!
So I looked a bit further, and found mention of the availability (thanks again!) of a replacement touchscreen, procured one for £24, and fitted it yesterday. I took the opportunity at the same time to fit an Apple CarPlay USB box (£125 for the complete kit), which was a perfect job to combine with it, given that so much of the same stuff needed to come out.
With many thanks once more, and all the best; JS.
Just one last comment, which I’d meant to include above: once I reached the critical final stage of removing the old screen from the bezel, I was worried about damaging or even cracking the latter by prying it. So I warmed up each edge progressively with a hairdryer to soften the original adhesive, then used a small plastic phone screen pry-bar on the INSIDE of the bezel to guard against marking it. This worked really well, and once the tool was fully underneath the full width of the bezel recess in one position I was then able to work the heat and the ‘blade’ around the full perimeter to fully detach the screen.
From the UK I bought my part here: https://www.ebay.co.uk/itm/384585599701
[if you also fancy upgrading your infotainment system to Apple CarPlay at the same time – extremely easy as you have access to almost everything you need once the screen assembly is removed – a reliable source for the kit is here: https://www.amazon.co.uk/gp/product/B091F91LMP/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1%5D
