Note: By turning off Lock-on-Road you also turn off the GPS position error filtering.
The position shown on the map will be subject to all position errors and position
fluctuations.
5.7.6 User data management
Everything that was saved (pins, My POIs, Favourites, track logs etc.) or modified
(Settings, History lists) since Uniden Navigation was installed is stored in a user
database located in the internal memory of the GNS8430/8435. Here you have
options to save, restore or reset the database or parts of it.
5.7.6.1 Backup Data
You can make a safe copy of the whole user database on the memory card.
Tap this button to copy all user data and settings on the memory card. The backup
is always created with the same file name; so backing up data will always overwrite
previous backups.
Tip: If you wish to keep more versions of the user database, or you wish to save one
particular state (e.g. saved POIs and track logs of your holiday), look for the backup
file on the SD card, rename it, or save it to your PC.
Tip: If you move to another GNS8430/8435, and you wish to keep your data and
settings, make a backup, remove the card, insert it into the other GNS8430/8435,
then return to this Settings page, and push the Restore Data button as described in
the next section. Uniden Navigation will then restart, and all your previous POIs, track
logs, settings, city and find history lists will also appear on the new GNS8430/8435.
5.7.6.2 Restore Data
If you have accidentally deleted things, or you have created a number of temporary
items and you do not wish to delete them one by one, you can tap this button to
restore the state of Uniden Navigation to the latest backup.
By tapping this button you will lose all of the changes made since the time of the
latest backup. Uniden Navigation will warn you about this before overwriting the
current database with the backup.
