TomTom Diagnostic Screens
Many TomTom models have a startup diagnostic screen that shows information about the unit's hardware, software, memory, and other details.
The sample image shows the diagnostics screen for a TomTom GO 510.
On models with an SD card, you can use the following instructions to display the diagnostics screen:
- If the unit is on, switch it off.
- Remove the SD card
- Press and HOLD the power button for several seconds.
After a few moments, a diagnostics screen similar to the one shown above should be displayed. The screen will stay for as long as you hold the power button.
Here is some example text from a TomTom GO 510:

I haven't found out how to access the diagnostic screens on models that use a hard drive instead of an SD card (e.g., GO 700, GO 910, etc.). If you come across it, please let me know so I can update this page.
