Touchscreen Calibration
TomTom GPS Navigation Device
Severity: MinorWhat Does This Error Mean?
Your TomTom touchscreen is registering taps in the wrong location — what you tap is not what you select. This is a calibration drift, common after software updates or long-term use. On older resistive-screen TomTom models, there is a built-in calibration tool. Newer capacitive models rarely need calibration and usually just need a restart.
Affected Models
- TomTom ONE (older resistive screen)
- TomTom XL (older resistive screen)
- TomTom START series
- TomTom Via series
- All TomTom GPS devices
Common Causes
- Touch calibration drift on resistive screen models
- Screen protector causing touch offset
- Software glitch after update
- Moisture affecting touch accuracy
- Screen damage causing touch point shift
How to Fix It
-
Restart the device — this often resolves temporary touch offset caused by software.
A software glitch after an update can shift touch point registration. A restart clears this.
-
Remove any screen protector and test the touch directly on the glass.
Poor-quality or thick screen protectors can shift touch registration by a few millimetres.
-
On older TomTom models (ONE, XL), access touch calibration via Settings > Calibrate Screen.
Resistive screens require periodic calibration. Follow the on-screen instructions and tap the targets precisely.
-
Ensure the screen is completely dry before touching it.
Moisture on capacitive screens causes erratic or offset touch response.
-
If calibration fails or is not available, perform a factory reset.
A factory reset resets all touch settings and often resolves persistent calibration issues on both screen types.
When to Call a Professional
If the touchscreen is consistently offset and calibration does not fix it, the touch digitizer may be failing. This requires professional screen replacement — contact TomTom support or a repair specialist.
Frequently Asked Questions
Why does my TomTom tap in the wrong place?
On older resistive-screen models, the calibration has drifted and needs resetting. On newer capacitive-screen models, a screen protector or software glitch is usually responsible. Restarting and removing any screen protector fixes most cases.
How do I access calibration mode on TomTom?
On older resistive-screen models, go to Settings > Calibrate Screen. On newer capacitive-screen models, there is no manual calibration tool — a restart or factory reset is the fix. If settings are inaccessible because touch is too inaccurate, use the pinhole reset button.
