Use this procedure only in case of real need.
If your navigation system (TS8511) has a not proper behaviour may need a recovering. You can do it by following these steps:
- Download the following archive. ZIP and extract the folder "NNG"
- Connect the navigator to the PC via the USB cable and switch it on.
- The computer may have to be rebooted due to the installation of the drivers: just do it.
- Two removable disks will be detected and shown into the "My computer" folder: one is related to the Flash Memory (the internal PND memory), the other to the SDCard (the removable memory of PND).
- Format (FAT32) the removeble disk Flash Memory (you can recognize it from the NNG folder's presence)
- Copy "NNG" folder just unzipped into root of Flashmemory.
- Disconnect the PND and unplug the USB cable.
- By restarting the PND via the "Reset" button positioned at the rear of the device, the navigation application will start automatically.
- If your PND is not responding properly to inputs, Touch Screen may need a recalibration.
It is recommended to accurately follow these steps in order to not compromise the functionality of the navigator and invalidate the warranty.
