Reset a Frozen Infotainment Screen

Last updated: June 10, 2026

If the central touchscreen on your Cupra Formentor (KM, 2020–Present) has frozen, gone black, or stopped answering your taps, you can force a reboot from the driver’s seat in about a minute — no tools, no garage.

Which system is in your Formentor

Cupra’s standalone SUV runs the VW-group MIB3 infotainment: a floating, frameless glass touchscreen (10″ on most trims, 12″ on the VZ) paired with the Cupra Digital Cockpit. There is no physical rotary knob — volume and home are the touch slider and buttons below the screen. The Formentor was a launch-era car for this platform, and early KM units were well known for the main unit rebooting on its own, freezing, and sometimes ending up on a permanent black screen. SEAT/Cupra and VW issued firmware that cured most cases, so a freeze is almost always software, not a failed panel.

Soft reset (reboot) the touchscreen

Do this parked, ignition on so the unit stays powered.

1. Locate the power/volume control below the screen (the touch on/off button and slider).
2. Press and hold it.
3. Keep holding for about 10–15 seconds until the display goes fully black and the CUPRA logo appears.
4. Release and give it 30–60 seconds to reload the home screen, radio, and any phone projection.

It is exactly like restarting a phone — a stuck process clears and everything else is left as it was.

Will this erase anything? No

The hold-to-reboot is completely safe. It does not wipe radio presets, navigation favourites, paired phones, Cupra Connect logins, or your driving-mode and Digital Cockpit layouts. The system simply reloads. Do it as often as you need.

If the screen stays frozen

• Hold longer. If the first attempt didn’t reach the CUPRA logo, repeat and hold up to 30 seconds.
• Lock and walk away. Switch off, lock with the key, leave it five minutes so the electronics sleep, then unlock and restart.
• Remove a card or USB. A corrupt SD card or USB stick can hang the MIB3 on boot — pull it and reboot.
• Update the software. If the Formentor reboots itself or keeps landing on a black screen, you are likely on early firmware; a Cupra dealer flashing the latest build is the documented fix for the launch-era bugs.
• Last resort: pull the infotainment fuse for about 10 seconds. The display unit sits on a low-amp fuse in the dash/passenger fusebox; the handbook gives the exact position.

Factory reset (erases data)

A factory reset is separate from a reboot and only worth doing if you are selling the car or chasing a deep, persistent glitch. Go to Menu → Settings → System → Factory settings. It erases presets, paired phones, Connect accounts, and saved destinations, so only do it deliberately.

Frequently Asked Questions

My Formentor screen keeps rebooting and went black — is that a known fault?

Yes. Early KM cars suffered reboot loops that could leave the screen permanently black. The fix is a Cupra dealer software update; the hold-to-reboot clears the immediate freeze in the meantime.

There’s no knob — how do I force the restart?

The Formentor uses a touch on/off and volume control under the screen instead of a rotary. Press and hold that for 10–15 seconds until the CUPRA logo shows.

Will rebooting delete my Cupra Connect data or presets?

No. The reboot keeps presets, favourites, paired phones, Connect login, and drive-mode settings. Only the menu Factory settings option clears them.

Is it safe to drive with the screen frozen?

Yes. The MIB3 unit is separate from the engine and driving systems — you only lose audio, navigation, and projection. Reboot once you are safely parked.

The Digital Cockpit froze as well — same fix?

Usually. The driver display and centre screen share the MIB3 platform, so the touchscreen reboot normally restores the cluster too. If only the cockpit stays stuck, cycle the ignition fully.

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