ScreenTune Support and Remedies

Effective August 16, 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.

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.

CategoryExamples
Installation helpUSB not recognized, progress-screen failure, or incomplete install
Product correctionA promised tweak does not work as documented
Recovery assistanceUsing REMOVE from the matching ScreenTune USB or troubleshooting a partial restore
Package deliveryReplacing an incomplete, corrupted, or lost download
In-window firmware overwriteRe-installation guidance when a Mazda update overwrites the changes during the support period

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 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 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 will review the replacement unit and reissue a compatible package at no charge when ScreenTune supports that firmware, region, and infotainment generation. Reinstall, repair, uninstall, and recovery rights for entitled releases do not expire.

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.

SituationPractical resolution
Change of mind within 14 days after purchaseFull refund; installation does not end the promise; the license and related entitlements then end
Download is incomplete or corruptedCorrected download at no cost
Package will not install on the compatible car Miatafy confirmedCorrection/replacement or full refund
Owner-supplied USB failsPreparation help; replacement hardware is not included
Different or inaccurate vehicle details were suppliedReviewed individually; voluntary refund may be refused to the extent the problem was caused by the inaccurate details
Change of mind after 14 daysReviewed individually; use the included uninstaller if installed

The request process and statutory context are explained on Cancellation and Withdrawal.

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.

The 90-day hands-on support promise does not cover unrelated hardware failures, unsupported firmware, a vehicle that does not match the intake, 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.

Email support@miatafy.com with:

  • the Stripe receipt or ScreenTune reference;
  • a description of the issue; and
  • photos, video, or logs when they show the problem.

Typical response time is within 48 hours. Support is also available by phone at +1 925-481-4495.

  • 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.
