Reset a Frozen Infotainment Screen

Last updated: June 12, 2026

If the touchscreen in your Kia Stonic (YB, 2017–Present) has frozen, gone black, dropped CarPlay or stopped responding to taps, you can force the head unit to reboot yourself in under a minute — no tools and no garage visit.

Which system the Stonic uses

The Stonic shares its head unit with the Rio it’s based on: Kia’s floating Display Audio / UVO screen — 5-inch on base cars, a 7-inch UVO touchscreen on most, and an 8-inch Kia Connect navigation display on higher facelift trims. All are touch-operated with a power/volume rotary knob on the left and hard shortcut keys. A frozen Stonic screen is a software lock-up in the head unit; engine, lights and climate keep working because only the display has stuck.

Soft reset (reboot) the screen

Park with the ignition on so the unit stays powered.

1. Find the power/volume knob on the left of the screen (press to mute).
2. Press and hold it in.
3. Keep holding for about 10 seconds until the screen goes black and the Kia logo appears.
4. Release the knob.
5. Allow 30–60 seconds for the home screen, radio and camera to reload.

Many Stonics also have a small pinhole RESET on the bezel near the knob. Use a straightened paperclip on the recessed button for about 5 seconds until the screen blacks out — same reboot.

Safe — it loses no data

This reboot is harmless. It does not wipe radio presets, paired phones, navigation favourites or settings — the unit simply reloads its software. Repeat as needed.

If it stays frozen

• Hold longer. If 10 seconds did nothing, retry for a full 20–30 seconds.
• Cycle the ignition. Switch off, open the driver’s door, lock the car, wait a couple of minutes, then unlock and restart.
• Suspect the phone link. If freezes happen with CarPlay or Android Auto, unplug, swap to a known-good USB cable and re-pair.
• Update the software. Recurring Stonic freezes and “map centering” hangs are fixed by a Kia firmware/map update from the Kia Update site or a dealer.
• Disconnect the battery. As a last resort, disconnect the negative (−) terminal for 10 minutes and reconnect.

Factory reset (erases data — rarely needed)

Separate from the reboot, and only for selling the car or clearing a persistent glitch. On the touchscreen go to Setup → General → Reset, or Settings → System → Restore Factory Settings on navigation units, and confirm. It wipes paired phones, presets, navigation favourites and settings back to factory defaults.

Frequently Asked Questions

Will rebooting my Stonic lose my presets and paired phone?

No. The knob-hold and pinhole only reload the software — presets, navigation favourites and pairings stay. Only the factory reset in the menu clears them.

Is the Stonic head unit the same as the Rio’s?

Yes, essentially. The Stonic is built on the Rio platform and uses the same Display Audio / UVO unit, so the volume-knob reboot, pinhole reset and menu paths are identical.

Where is the reset pinhole on the Stonic?

It is a tiny recessed hole on the screen bezel near the power/volume knob, marked RESET. If your trim doesn’t have one, use the knob-hold instead.

My Stonic keeps losing Apple CarPlay — will a reboot help?

It often clears it for that drive. For a lasting fix, use a quality USB-A data cable, re-pair the phone, and ask a Kia dealer about the latest UVO software.

Is it safe to drive with the Stonic screen frozen?

Yes. The head unit is independent of the engine and brakes — you only lose audio, phone, navigation and the camera. Reboot when parked.

If a warning light or fault message stays on the dash after the reboot, the car may have stored a diagnostic trouble code — you can look it up on autodtcs.com.
