Operation Manual

• Options: this button leads to a settings screen where you can set up the track

logging parameters:

• Create NMEA/SIRF log: independently of the normal track log, you can instruct

V7 Navigation to record the native GPS data received from the GPS device.

The saved data will be in NMEA format. These logs are saved as separate text

files on the SD card (if inserted), and they cannot be shown or replayed in V7

Navigation. They are for post-processing needs, should you have any. Be

careful when saving native GPS data, as it can soon eat up available memory.

The rest of the controls apply to the normal track logs.

• Update interval is how often track points will be saved. Position information is

normally received once a second from the GPS. If you do not need such a

detailed log, you can increase this number to save track log space.

• Enable auto-saving: when auto-saving is enabled, you do not need to turn

track log saving on and off manually. V7 Navigation will automatically start

recording the track log as soon as GPS position is available.

• Current autosave track size: this figure shows how much memory is used by

the automatically saved track logs.

• Limit track DB size: here you can set whether or not to maximize the size of

the database where the automatically saved track logs are kept.

• Maximum track database size: here you can set the maximum database size

if the track database size limit is enabled using the previous switch.

5.7 Manage POI (Points of Interest)

Here you can set all the parameters of POIs that you have created and the visibility

of the built-in POIs that come with the map.

Manage built-in POI visibility

The maps in V7 Navigation come with a huge number of POIs. Displaying all of them

would make the maps too crowded (to see how POI items are shown on the map

see Page ). In order to avoid that, you can decide which POI groups to show and

which ones to hide on the map. V7

Navigation has a multi-level POI category

system. You can set the visibility of the top two levels. All levels below that will be

shown or hidden according to their respective category (i.e. you can set the visibility

of Petrol Stations in the Services category, but all brands listed under that will either

be shown or suppressed together).
