Also,
can anyone who is familliar with etrex 30 tell me the best way on the course to reset my tracks every day so there will be a gpx file for each day? is it even possible? preferably without having to reload the aztr track.
thanks!
I believe the track is saved to the memory card once the GPS is powered down. So just turn it off each night and it should save the track as a file to the SD card. Here is a quote from a post I made in the CTR forum (hope it helps):
1. It records to Internal Memory when you have the Track Log On radio button selected under: Tracks > Track Log ON or OFF.
2. It will record to internal memory and to the SD when you have done step 1 above and also checked the "Log track to data card" under: Tracks > Setup > Data Card Setup > Log Track to Data Card.
It will NOT record to SD without BOTH 1 and 2 above selected to save track.
Yes it saves both to internal memory and SD but you can clear the internal memory of the saved track easily when it starts getting full or just have the "Wrap when full" checked under: Tracks > Setup > Wrap when full.
This internal memory is additional storage to your uploaded tracks so if you have uploaded all available memory it saves some space for the tracks to be saved to internal memory. The tracks it saves to internal memory contain very basic information. The tracks saved to the SD contain the detailed information such as speed, alt. etc.
