Just a warning to all that dont know. If you hit the adjust button on the first screen after the gps start up (the rubbish bin, yes/no) it will happily delete the file that is in there, without telling you that you are about to delete one of the best sessions you have ever had

I was away for 2 days and didnt upload the results until back at home, then realised there was only one file in there.
As i like to clear the numbers from the previous day, i was not aware that you also delete the whole file from the previous day too. Real shame that it doesnt let you confirm what is going to be deleted, so hopefully Locosys can consider this in an upgrade.
Ahh well i guess ill have to go back ant try it again. It was the best NM ever, I promise!
