Device Overheating
TomTom GPS Navigation Device
Severity: ModerateWhat Does This Error Mean?
Your TomTom has reached a dangerously high temperature and has shut down or is warning you. GPS devices in cars can overheat quickly in direct sunlight — especially in summer. This is a protective shutdown, not a hardware failure. Cooling the device restores normal operation.
Affected Models
- TomTom GO 520
- TomTom GO 620
- TomTom GO 5200
- TomTom GO 6200
- All TomTom GPS devices
Common Causes
- Device left in direct sunlight through the windshield
- Parked car in summer with windows closed
- Ventilation blocked by a bad mount position
- Continuous use in very hot climates
- Internal fan failure (rare — most GPS devices have no fan)
How to Fix It
-
Remove the device from the car or move it out of direct sunlight immediately.
Car interiors can reach 80°C (180°F) in direct sun. This is the most common cause of GPS overheating.
-
Allow the device to cool for 10–15 minutes before powering it on again.
Using an overheated device before it cools can cause further damage. Let it reach room temperature first.
-
Use a sun shade on your windshield when the car is parked.
A windshield sun shade dramatically reduces interior temperature and protects all electronics in the car.
-
Remove the device from the mount when leaving the car.
Taking the GPS with you prevents it from sitting in an oven-temperature car. This also prevents theft.
-
Mount the device lower on the windshield where it receives less direct sun.
A lower mount position is partly shaded by the dashboard and runs cooler than a top-centre position in full sun.
When to Call a Professional
Overheating from sun exposure is environmental, not a device fault. If the device overheats within minutes of normal indoor use, internal hardware may be failing — contact TomTom support.
Frequently Asked Questions
Can overheating permanently damage my TomTom GPS?
Occasional overheating from sun exposure rarely causes permanent damage. Repeated extreme overheating can degrade the battery and reduce its lifespan over time. Always store the device in a cool place to protect it.
What temperature can a TomTom GPS handle?
Most TomTom devices operate between -20°C and 60°C (-4°F to 140°F). Storage in a parked car in summer can easily exceed 60°C. Always remove the GPS from the car in hot weather.
