•  Maximum track database size: here you can set the maximum database size
if the track database size limit is enabled using the previous switch. 
•  Create NMEA/SIRF log:
 
 independently of the normal track log, you can instruct 
Clarion to record the native GPS data received from the GPS device. Clarion is 
capable of working with GPS devices using either the NMEA or the SiRF 
protocol, so the saved data will be in one of these formats. These logs are 
saved as separate text files on the memory card (if inserted), and they cannot 
be shown or replayed in Clarion. 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 current route. 
 
Recalculate 
This function repeats the route calculation based on the same settings as used to 
calculate previously. This possibility is typically used when automatic off-route
