• 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

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