waypoints too/from lowrance hds-5m?

[jw]

i cant this to work, the unit can save waypoints to a 2 gig sd card
but i cannot view the files under either windows or linux. Do lowrance use their
own file system? any help appreciated.

hmm, file system is reported as FAT16, maybe the card got corrupted somehow, could happen for a lot of reasons, did you try to use any data recovery software yet? ZAR is very good.

i made a bit of progress, i plugged the card into a different pc with built in sd card slot
and i can see the file fine. must be incompatibile with the external sd reader for some
reason. still researching the options as i have mapsource charts on my pc from a previous
garmin plotter...

you could email the charts to yourself or upload to a free file host and use the pc whit the compatible card reader to transfer them back.
