Repair Guide: ND Mazda MX-5 touchscreen cracks / de-lamination

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!

      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.
