Each unit has tools to configure the operation of GPS devices or debug them.
To use them, go to Unit Menu - Tools.
The following tools are available:
Send standard commands to your GPS device for remote control and configuration.
View messages received from the device, logs about connection, errors, unit editing. If you need deep debugging, you can view the raw data that the device sent.
Setbox and some Toolbox features are not available for devices in the Legacy category.
