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.
