How to Do a Hard Reboot on Your GMC Infotainment System
When a soft reset (holding the power/volume knob) doesn't clear a persistent infotainment glitch, a hard reboot — fully cutting power to the module rather than just restarting the display — reaches deeper software states that a simple button hold can't touch.

Try a Soft Reset First
Before pulling any fuses, hold the power/volume knob (or dedicated power button) for 10-15 seconds to force a simple restart. This resolves the majority of minor freezes and glitches without needing a full power cycle.
Hard Reboot Via Fuse
If a soft reset doesn't help, locate the infotainment/radio fuse in your fuse box diagram (check your owner's manual for the exact location and fuse number) and pull it for about a minute before reinserting. This fully cuts power to the module, forcing a complete reboot of its internal software.
Hard Reboot Via Battery Disconnect
Alternatively, disconnecting the vehicle's 12-volt battery for about a minute achieves a similar full power cycle, though it will also reset other settings tied to constant power (like the clock). This is a reasonable option if you're unsure of the correct fuse location.
What to Expect Afterward
After reconnecting power, the infotainment system may take 30-90 seconds or longer to fully boot up and initialize, especially after a hard reboot. Some settings not stored in permanent memory (like the clock) will need to be reset manually.

Frequently Asked Questions
Will a hard reboot delete my paired Bluetooth devices?
Generally no — a hard reboot power-cycles the module but typically preserves saved settings and pairings, unlike a full factory reset performed through the Settings menu, which does clear that data.
Is it safe to pull a fuse while the vehicle is running?
It's best to do this with the vehicle off and the key removed to avoid any unexpected electrical behavior while working in the fuse box.
How long should I wait before reinserting the fuse?
About one minute is generally enough to fully discharge the module's residual power and force a clean reboot; waiting longer doesn't provide additional benefit.
What if a hard reboot doesn't fix the problem?
If the issue persists after both a soft and hard reset, it likely points to a software bug needing an update, a stuck configuration needing a full factory reset, or a genuine hardware fault requiring dealer diagnosis.
