Reset the navigation “save” folder (MN3)

The save folder stores various user-related data, including your settings, routes, history and GPS data. Sometimes, this data may prevent the navigation software from getting a GPS fix or it takes a very long time. This can be solved by reseting the save folder – although some of the user data may be lost (settings and favorites, for example).

How to use

Prerequisites:
– a tablet, laptop or desktop equipped with an USB port, containing the new maps
– USB flash drive, FAT32 formatted, max. 32 GB capacity, ideally with an indicator light

Note: An USB flash drive with an indicator light is preferred since the light will be the only indicator of the ongoing read and write operations performed on the flash drive.

Step 1. Download Navi Save Reset from the link in the table above.

Step 2. Unzip the archive and copy the folders to the root of the flash drive – the folders should be the first to be seen upon accesisng the flash drive.

Step 3. Put the flash drive in the USB port, wait for the Media Nav to boot and the backup will start automatically.

Step 4. When the indicator light of the flash drive stops blinking for 10-15 seconds or, if there is no indicator light, after about 3 minutes, you can unplug the flash drive and turn off the Media Nav.

At this point, the save folder on the Media Nav unit will be empty, and a backup copy of the folder will be found on the flash drive, together with a file named SaveReset_Log.txt – this is the generated log.

From this point onwards, the steps are optional and detail restoring your favorites and POI from the save folder backup.

Step 5. Download Navi Restore POI from the link in the table above.

Step 6. Unzip the archive and copy the folders to the root of the flash drive.

Step 7. Copy the files containing your favorites and POI from the backup to the /nng_rw/save folder on the flash drive.

Step 8. Put the flash drive in the USB port, wait for the Media Nav to boot and the backup will start automatically.

Step 9. When the indicator light of the flash drive stops blinking for 10-15 seconds or, if there is no indicator light, after about 3 minutes, you can unplug the flash drive and turn off the Media Nav.
