hi all,

Twice in the past week i've come home to plug in my GPS's SD card and find no file from my day's sailing.

I noticed on the second session that my GPS was not able to acquire a signal....i presume this is what also happened the first time around.

Has anyone else had similar problems?

Does anyone have any trouble shooting ideas?

Thanks in advance.

Didnt write to card yes? if so, check data logger, to see if it filled this. Download that to card and take a look.
Why they do this I am not sure, even my GT-11 does it every six months or so. Pays to clear data logger before each session as a back up.
Others with guru status may have a solution.
