Since years ago, TwoNav is compatible with maps in ECW format.
Due to an error, first Aventura units don't include the required files to read this format.
Current units have this problem solved, but if your Aventura doesn't allow to open ECW maps, you just have to add the missing files in your device following next steps:
- Connect TwoNav Aventura to the PC with the USB cable. You will see 'local disc' (internal memory of the device) and 'removable disk' (SD card) appear in your system.
- Download the file clicking here.
- Unzip the content and save it inside 'TwoNav' folder of the 'local disk', where TwoNav_Aventura.exe is also placed.
- Disconnect Aventura from the PC and start it normally.
