The most common problem people have with updating their d10 is downloading the wrong version of the d10 Updater app.
There are separate versions of the application for 32 (x86) and 64 (x64) bit systems.
To check which version you need:
- Right click on the windows menu icon in toolbar.
- Choose "System"
- Check the "System type" in "Device specification"
Next up the d10 needs to be set to receive an update. To do this power on the d10 and when it says "RACEGEEK" press the LEFT ARROW on the d10. It will now say "START UPLOAD".
