TwoNav Sportiva has three software levels:

• Eboot: Starting component which runs the operating system.
• Operating system: Executed under TwoNav and controling the more basic operations of the device.
• TwoNav: Executed over the operating system and interacting with user.

Normally, software updates are for TwoNav, but eboot and operating system can also have updates.

Important:

• The user should know that this is a delicate process. It must be applied correctly, otherwise it could leave the unit unusable.
• In order to avoid losing data during the updating process, please copy all your personal files contained in 'TwoNavData/Data' to computer (security copy).
• Updates might take some minutes, you might need to wait so left the device working until further steps are being indicated.
• Enough battery is needed to update the operating system, at least 30 min.
• Battery cover must be closed, so no irreparable damages at the operating system might be applied.
