I give up. In the faint hope that one of you knows some magic...........

I made .gpx files for the lakes on the AGFC website, for the brushpiles/tops/whatever they have listed.

I saved the Greeson .gpx file to an SD card.

I put the SD card into the card slot on my Humminbird 768. I turned it on.

Nothing.

There is NO menu option for 'importing files'. None. There is one for exporting, which I find weird.

Man, it's hard to be poor.

I know how to manually enter, but there are 900 of 'em!!!

Any clues?? Leaving tomorrow.

Thanks.
