Symptoms
- Screen shows the startup logo repeatedly
- System works briefly then restarts on its own
- Problem is constant or happens every few minutes
- May coincide with other electrical symptoms
Likely causes
- CommonSoftware crash loopA corrupted setting or app can cause the system to crash and restart in a cycle.
- PossibleUnstable 12V power supplyVoltage fluctuations from a weak battery or alternator can cause sensitive electronics to reboot.
- PossibleOverheating head unitUnits that run hot, especially in direct sun, can shut down and restart to protect themselves.
- Less commonFailing hardware inside the head unitInternal component failure can cause instability that only a repair or replacement fixes.
What to do
- Let the car sit off for several minutes, then restart to see if a single fresh boot holds.
- Have the 12V battery and charging system voltage tested, since unstable power is a common hidden cause.
- Note whether the rebooting is worse on hot days or after the car has been parked in direct sun.
- If you recently connected a new phone, USB drive, or accessory, disconnect it and see if reboots stop.
- Check if a pending software update might resolve a known crash bug; ask your dealer.
- If it reboots constantly even when parked and cool, avoid relying on backup camera or safety features tied to that screen until it's fixed.
When to call a pro
Persistent reboots should be diagnosed by a dealer, since they can involve battery voltage, software, or head unit hardware.
