Thanks to Pascal Lemée for providing a link to a replacement touch-screen (the glass screen cover and “digitizer” that overlays the LCD presentation screen), for those experiencing delamination caused by high temperatures within the unvented air cavity between the two screens. It can currently be procured for about $20, including S/H using the link below, but even if you source it elsewhere, this provides the necessary details for comparison purposes (7 Inch, 36 Pin, Glass Touch Screen TM070RDZ38).

He also provided a link for an excellent repair guide (alternate google doc), written up with many photos, by Tyler Watthanaphand.

Another alternative as of October 2022, is to order the screen assembly (complete with the glass touch-screen and “digitizer”, the LCD presentation screen, and the silver surround frame) from Mazda for around $80. Warranty costs were mounting for replacing perfectly fine CMUs (at $1,000 to $2,000), simply because the screens were delaminating, so Mazda finally made screen-only replacements available to their dealers.
Although Mazda started using an improved version of the CMU (Connect 2.0 with better processor and shielding, higher-res LCD screens and 50-pin ribbon cables for the digitizer) in the MX-5 for MY 2018+, it is believed that all years of 124 Spiders used the same CMUs as the 2016 – 2017 MX-5 vehicles (Connect 1.0), so the part to order with the correct 36-pin ribbon cable for the digitizer, circuit board with smaller silicon chip at the bottom and lower- res LCD screen, should be Mazda part # D0YP-61-1JZ. Refer to an abbreviated version of TSB 09-136/22 for details.
Note: If the new screens are subjected to the same high temperature conditions that originally resulted in delamination, since the design/process hasn’t changed, the same could happen once again.

Thanks Pascal and Ameridan! Looking forward to hearing more about this. My 2017 Abarth is coming up on 80k mikes and this is the only flaw. I’m hoping to fix this one day soon.

Great information. The link is legit, but you have to scroll down to find it. The detail he gives is great with several pictures. So very easy to follow. If you can somehow grab it and put it on your site that would be awesome. Kudos to Tylerwatt12 !!!

Since we’ve determined that the link is fine (his link to his resume seems to trigger the Malwarebyte message though), I’ve updated the url and edited the article somewhat. Thanks Mike.
Seems Tyler has found an easier method to access the CMU too!

I’ve extracted Tyler’s Repair Guide into a google doc here also Ameridan if you are worried about the site. I didn’t see anything suspicious though and we should still show him some love for this. I can maybe repost to some forums too
