ScreenTune Support and Remedies
Effective October 28, 2026.
ScreenTune includes 90 days of hands-on support and one year of software updates. Both periods begin on delivery. These are additional commercial promises from DenyaDev LLC, doing business as Miatafy; they do not shorten mandatory consumer rights or the remedies available for a digital product that is defective, late, or not as described.
What the 90-day support promise covers
Section titled “What the 90-day support promise covers”Support runs for 90 days from delivery and covers the licensed vehicle and firmware confirmed by the installer. For a download, delivery occurs when Miatafy sends a working download link. For a mailed USB, delivery is the carrier’s recorded delivery date.
| Category | Examples |
|---|---|
| Installation help | USB not recognized, progress-screen failure, or incomplete install |
| Product correction | A promised tweak does not work as documented |
| Recovery assistance | Using REMOVE from the matching ScreenTune USB or troubleshooting a partial restore |
| Package delivery | Replacing an incomplete, corrupted, or lost download |
| In-window firmware overwrite | Re-installation guidance when a Mazda update overwrites the changes during the support period |
One year of updates begins on delivery
Section titled “One year of updates begins on delivery”The purchase includes ScreenTune releases published through the one-year anniversary of delivery, inclusive, when they apply to the purchased edition, licensed vehicle, and supported firmware. Eligible releases include bug fixes, performance improvements, and improvements to included features.
AA Touch is an included ScreenTune feature, not a separately priced add-on. Existing ScreenTune customers whose package does not already include AA Touch receive an updated package by email, even after the normal update-eligibility date. Customers who miss the message can request it from My ScreenTune or through support.
The update promise does not automatically include separately priced editions, add-ons, new hardware, Mazda firmware, or another infotainment generation. Release date determines eligibility. A customer may request an eligible release later, from My ScreenTune or through support, even when it was not downloaded during the update year.
There is no subscription, automatic renewal, forced update, or automatic charge. ScreenTune continues working when update eligibility ends. The customer keeps a perpetual license to every version released for that order during the eligibility period. Later paid upgrades are optional.
Update eligibility after day 90 supplies eligible software releases. It does not extend hands-on installation support unless mandatory consumer rights or a separate support arrangement applies.
Re-downloads, transfers, and replacement CMUs
Section titled “Re-downloads, transfers, and replacement CMUs”A lost or expired link does not end the license. While Miatafy continues operating ScreenTune and retains the artifact, it will provide a fresh link to the latest package the customer is entitled to at no charge. A fresh link does not restart support or add later releases. Customers should retain their own copy.
The customer may transfer the license with the sold vehicle or uninstall ScreenTune and move the entitlement to another compatible authorized vehicle. Miatafy charges no transfer fee. The license cannot remain active on the old vehicle after it moves, and the existing support and update dates do not restart.
Replacing the CMU in the same vehicle does not consume a transfer. Miatafy reissues a package for the replacement unit at no charge when ScreenTune supports that firmware, region, and infotainment generation. The installer checks the firmware on the car before making a change. Reinstall, repair, uninstall, and recovery rights for entitled releases do not expire.
Change-of-mind refunds
Section titled “Change-of-mind refunds”Miatafy offers ScreenTune download purchasers a full change-of-mind refund when requested within 14 days after purchase. Delivery or installation during those 14 days does not end this promise. After a refund, the buyer must stop using or sharing the package and use the included uninstaller if it was installed.
| Situation | Practical resolution |
|---|---|
| Change of mind within 14 days after purchase | Full refund; installation does not end the promise; the license and related entitlements then end |
| Download is incomplete or corrupted | Corrected download at no cost |
| Car setup or the package build shows ScreenTune does not support the vehicle | Full refund |
| Package will not install on a Gen 6 Mazda Connect car running firmware v74.00.324 | Full refund, or a corrected or replacement package if the buyer prefers |
| Owner-supplied USB fails | Preparation help; replacement hardware is not included |
| Different or inaccurate vehicle details were supplied | Reviewed individually; voluntary refund may be refused to the extent the problem was caused by the inaccurate details |
| Change of mind after 14 days | Reviewed individually; use the included uninstaller if installed |
The request process and statutory context are explained on Cancellation and Withdrawal.
Mandatory remedies for a problem
Section titled “Mandatory remedies for a problem”The refund boundary above does not apply when mandatory consumer law says the digital product has a defect or was not delivered as agreed. Depending on the circumstances, a consumer may be entitled to:
- delivery of the product;
- correction or replacement at no cost, within a reasonable time and without significant inconvenience;
- a proportionate price reduction;
- termination and refund when the legal conditions are met; or
- compensation for a covered loss.
Miatafy normally starts by correcting or replacing the package. A buyer does not lose these rights merely because installation occurred or the commercial support or update period ended.
Outside the commercial support promise
Section titled “Outside the commercial support promise”The 90-day hands-on support promise does not cover unrelated hardware failures, unsupported firmware, a vehicle that does not match the details entered in car setup, problems introduced by third-party tools, phone/network pairing issues, dealer or warranty advocacy, or new support requests made after 90 days. Those limits do not excuse a defect in ScreenTune itself.
Requesting help
Section titled “Requesting help”Email support@miatafy.com with:
- the email address used for the order, or the Stripe receipt;
- a photo of Settings → System → About;
- a photo of what the screen showed, or a short description; and
- the contents of the ScreenTune USB as a ZIP.
Get help explains each item and how to zip the USB.
Typical response time is within 48 hours.
Safety and scope
Section titled “Safety and scope”- ScreenTune changes the infotainment system only, not braking, steering, airbags, stability control, powertrain, or emissions systems.
- Removing the startup disclaimer is a user-interface change and does not disable a vehicle safety system.
- The driver remains responsible for safe vehicle operation and avoiding distraction.
- Miatafy does not claim that a modification is undetectable by a dealer or manufacturer.
